glBindTexture
```
public static void glBindTexture(int target,
                                 int texture)
```
Binds the a texture to a texture target.
While a texture object is bound, GL operations on the target to which it is bound affect the bound object, and queries of the target to which it is bound return state from the bound object. If texture mapping of the dimensionality of the target to which a texture object is bound is enabled, the state of the bound texture object directs the texturing operation.

Parameters:

target - the texture target. One of:
TEXTURE_1D TEXTURE_2D TEXTURE_1D_ARRAY TEXTURE_RECTANGLE TEXTURE_CUBE_MAP
TEXTURE_3D TEXTURE_2D_ARRAY TEXTURE_CUBE_MAP_ARRAY TEXTURE_BUFFER TEXTURE_2D_MULTISAMPLE

```
Constructs a sequence of geometric primitives by successively transferring elements for count vertices. Elements first through first + count – 1 of each enabled non-instanced array are transferred to the GL.
If an array corresponding to an attribute required by a vertex shader is not enabled, then the corresponding element is taken from the current attribute state. If an array is enabled, the corresponding current vertex attribute value is unaffected by the execution of this function.

Parameters:

mode - the kind of primitives being constructed

first - the first vertex to transfer to the GL

count - the number of vertices after first to transfer to the GL

See Also:

Reference Page

glDrawBuffer
```
public static void glDrawBuffer(int buf)

Parameters:: n - the number of textures to create

glGenTextures
```
public static void glGenTextures(java.nio.IntBuffer textures)
```
Returns n previously unused texture names in textures. These names are marked as used, for the purposes of GenTextures only, but they acquire texture state and a dimensionality only when they are first bound, just as if they were unused.

Parameters:

textures - a scalar or buffer in which to place the returned texture names

See Also:

Reference Page

glGenTextures
```
public static int glGenTextures()

```
Unsafe version of: DeleteTextures

Parameters:

n - the number of texture names in the textures parameter

glDeleteTextures
```
public static void glDeleteTextures(java.nio.IntBuffer textures)
```
Deletes texture objects. After a texture object is deleted, it has no contents or dimensionality, and its name is again unused. If a texture that is currently bound to any of the target bindings of BindTexture is deleted, it is as though BindTexture had been executed with the same target and texture zero. Additionally, special care must be taken when deleting a texture if any of the images of the texture are attached to a framebuffer object.
Unused names in textures that have been marked as used for the purposes of GenTextures are marked as unused again. Unused names in textures are silently ignored, as is the name zero.

Parameters:

textures - contains n names of texture objects to be deleted

LWJGL note: The state that corresponds to the state variable may be a single value or an array of values. In the case of an array of values, LWJGL will not validate if params has enough space to store that array. Doing so would introduce significant overhead, as the OpenGL state variables are too many. It is the user's responsibility to avoid JVM crashes by ensuring enough space for the returned values.

Parameters:

pname - the state variable

glGetError
```
public static int glGetError()
```
Returns error information.
Each detectable error is assigned a numeric code. When an error is detected, a flag is set and the code is recorded. Further errors, if they occur, do not affect this recorded code. When GetError is called, the code is returned and the flag is cleared, so that a further error will again record its code. If a call to GetError returns NO_ERROR, then there has been no detectable error since the last call to GetError (or since the GL was initialized).

glPolygonMode
```
public static void glPolygonMode(int face,
                                 int mode)
```
Controls the interpretation of polygons for rasterization.
FILL is the default mode of polygon rasterization. Note that these modes affect only the final rasterization of polygons: in particular, a polygon's vertices are lit, and the polygon is clipped and possibly culled before these modes are applied. Polygon antialiasing applies only to the FILL state of PolygonMode. For POINT or LINE, point antialiasing or line segment antialiasing, respectively, apply.

Parameters:

face - the face for which to set the rasterizing method. One of:
FRONT BACK FRONT_AND_BACK

mode - the rasterization mode. One of:
POINT LINE FILL

                                   float units)
```
The depth values of all fragments generated by the rasterization of a polygon may be offset by a single value that is computed for that polygon. This function determines that value.
factor scales the maximum depth slope of the polygon, and units scales an implementation-dependent constant that relates to the usable resolution of the depth buffer. The resulting values are summed to produce the polygon offset value.

Parameters:

factor - the maximum depth slope factor

units - the constant scale

Acceptable values for src depend on whether the GL is using the default framebuffer (i.e., DRAW_FRAMEBUFFER_BINDING is zero), or a framebuffer object (i.e., DRAW_FRAMEBUFFER_BINDING is non-zero). In the initial state, the GL is bound to the default framebuffer.

Parameters:

src - the color buffer to read from. One of:
NONE FRONT_LEFT FRONT_RIGHT BACK_LEFT BACK_RIGHT FRONT BACK LEFT
RIGHT FRONT_AND_BACK COLOR_ATTACHMENT0 GL30.GL_COLOR_ATTACHMENT[1-15]

ReadPixels obtains values from the selected read buffer from each pixel with lower left hand corner at (x + i, y + j) for 0 <= i < width and 0 <= j < height; this pixel is said to be the i^th pixel in the j^th row. If any of these pixels lies outside of the window allocated to the current GL context, or outside of the image attached to the currently bound read framebuffer object, then the values obtained for those pixels are undefined. When READ_FRAMEBUFFER_BINDING is zero, values are also undefined for individual pixels that are not owned by the current context. Otherwise, ReadPixels obtains values from the selected buffer, regardless of how those values were placed there.

Parameters:

x - the left pixel coordinate

y - the lower pixel coordinate

width - the number of pixels to read in the x-dimension

height - the number of pixels to read in the y-dimension

format - the pixel format. One of:

`RED`	`GREEN`	`BLUE`	`ALPHA`	`RG`	`RGB`	`RGBA`	`BGR`
`BGRA`	`RED_INTEGER`	`GREEN_INTEGER`	`BLUE_INTEGER`	`ALPHA_INTEGER`	`RG_INTEGER`	`RGB_INTEGER`	`RGBA_INTEGER`
`BGR_INTEGER`	`BGRA_INTEGER`	`STENCIL_INDEX`	`DEPTH_COMPONENT`	`DEPTH_STENCIL`

type - the pixel type. One of:

`UNSIGNED_BYTE`	`BYTE`	`UNSIGNED_SHORT`	`SHORT`
`UNSIGNED_INT`	`INT`	`HALF_FLOAT`	`FLOAT`
`UNSIGNED_BYTE_3_3_2`	`UNSIGNED_BYTE_2_3_3_REV`	`UNSIGNED_SHORT_5_6_5`	`UNSIGNED_SHORT_5_6_5_REV`

                             int height)
```
Defines the scissor rectangle for all viewports. The scissor test is enabled or disabled for all viewports using Enable or Disable with the symbolic constant SCISSOR_TEST. When disabled, it is as if the scissor test always passes. When enabled, if left ≤ x_w < left + width and bottom ≤ y_w < bottom + height for the scissor rectangle, then the scissor test passes. Otherwise, the test fails and the fragment is discarded.

Parameters:

x - the left scissor rectangle coordinate

y - the bottom scissor rectangle coordinate

width - the scissor rectangle width

height - the scissor rectangle height

glStencilFunc
```
public static void glStencilFunc(int func,
                                 int ref,
                                 int mask)
```
Controls the stencil test.
ref is an integer reference value that is used in the unsigned stencil comparison. Stencil comparison operations and queries of ref clamp its value to the range [0, 2^s – 1], where s is the number of bits in the stencil buffer attached to the draw framebuffer. The s least significant bits of mask are bitwise ANDed with both the reference and the stored stencil value, and the resulting masked values are those that participate in the comparison controlled by func.

Parameters:

func - the stencil comparison function. One of:
NEVER ALWAYS LESS LEQUAL EQUAL GEQUAL GREATER NOTEQUAL

ref - the reference value

mask - the stencil comparison mask

glStencilMask
```
public static void glStencilMask(int mask)
```
Masks the writing of particular bits into the stencil plans.
The least significant s bits of mask, where s is the number of bits in the stencil buffer, specify an integer mask. Where a 1 appears in this mask, the corresponding bit in the stencil buffer is written; where a 0 appears, the bit is not written.

Parameters:

mask - the stencil mask

glStencilOp
```
public static void glStencilOp(int sfail,
                               int dpfail,
                               int dppass)
```
Indicates what happens to the stored stencil value if this or certain subsequent tests fail or pass.
The supported actions are KEEP, ZERO, REPLACE, INCR, DECR, INVERT, INCR_WRAP and DECR_WRAP. These correspond to keeping the current value, setting to zero, replacing with the reference value, incrementing with saturation, decrementing with saturation, bitwise inverting it, incrementing without saturation, and decrementing without saturation.

For purposes of increment and decrement, the stencil bits are considered as an unsigned integer. Incrementing or decrementing with saturation clamps the stencil value at 0 and the maximum representable value. Incrementing or decrementing without saturation will wrap such that incrementing the maximum representable value results in 0, and decrementing 0 results in the maximum representable value.

Parameters:

sfail - the action to take if the stencil test fails

dpfail - the action to take if the depth buffer test fails

dppass - the action to take if the depth buffer test passes

public static void glCopyTexImage1D(int target,
                                    int level,
                                    int internalFormat,
                                    int x,

                                    int border)
```
Defines a one-dimensional texel array in exactly the manner of TexImage1D, except that the image data are taken from the framebuffer rather than from client memory. For the purposes of decoding the texture image, CopyTexImage1D is equivalent to calling CopyTexImage2D with corresponding arguments and height of 1, except that the height of the image is always 1, regardless of the value of border. level, internalformat, and border are specified using the same values, with the same meanings, as the corresponding arguments of TexImage1D. The constraints on width and border are exactly those of the corresponding arguments of TexImage1D.

Parameters:

target - the texture target. Must be:
TEXTURE_1D

level - the level-of-detail number

internalFormat - the texture internal format. See TexImage2D for a list of supported formats.

x - the left framebuffer pixel coordinate

y - the lower framebuffer pixel coordinate

width - the texture width

border - the texture border width

                                    int internalFormat,

                                    int border)
```
Defines a two-dimensional texel array in exactly the manner of TexImage2D, except that the image data are taken from the framebuffer rather than from client memory.
x, y, width, and height correspond precisely to the corresponding arguments to ReadPixels; they specify the image's width and height, and the lower left (x, y) coordinates of the framebuffer region to be copied.

The image is taken from the framebuffer exactly as if these arguments were passed to CopyPixels with argument type set to COLOR, DEPTH, or DEPTH_STENCIL, depending on internalformat. RGBA data is taken from the current color buffer, while depth component and stencil index data are taken from the depth and stencil buffers, respectively.

Subsequent processing is identical to that described for TexImage2D, beginning with clamping of the R, G, B, A, or depth values, and masking of the stencil index values from the resulting pixel groups. Parameters level, internalformat, and border are specified using the same values, with the same meanings, as the corresponding arguments of TexImage2D.

The constraints on width, height, and border are exactly those for the corresponding arguments of TexImage2D.

Parameters:

target - the texture target. One of:
TEXTURE_2D TEXTURE_1D_ARRAY TEXTURE_RECTANGLE TEXTURE_CUBE_MAP

level - the level-of-detail number

internalFormat - the texture internal format. See TexImage2D for a list of supported formats.

x - the left framebuffer pixel coordinate

y - the lower framebuffer pixel coordinate

width - the texture width

height - the texture height

border - the texture border width

glViewport
```
public static void glViewport(int x,
                              int y,
                              int w,
                              int h)
```
Specifies the viewport transformation parameters for all viewports.
The location of the viewport's bottom-left corner, given by (x, y), are clamped to be within the implementation-dependent viewport bounds range. The viewport bounds range [min, max] tuple may be determined by calling GetFloatv with the symbolic constant VIEWPORT_BOUNDS_RANGE. Viewport width and height are clamped to implementation-dependent maximums when specified. The maximum width and height may be found by calling GetFloatv with the symbolic constant MAX_VIEWPORT_DIMS. The maximum viewport dimensions must be greater than or equal to the larger of the visible dimensions of the display being rendered to (if a display exists), and the largest renderbuffer image which can be successfully created and attached to a framebuffer object.

In the initial state, w and h for each viewport are set to the width and height, respectively, of the window into which the GL is to do its rendering. If the default framebuffer is bound but no default framebuffer is associated with the GL context, then w and h are initially set to zero.

Parameters:

x - the left viewport coordinate

y - the bottom viewport coordinate

w - the viewport width

h - the viewport height
