Module glitter::types

Contains miscellaneous general-purpose OpenGL types.

Structs

BufferBits	The possible buffers that the active framebuffer may contain.
Color	A color, with floating-point RGBA components.
Viewport	An OpenGL viewport, with an origin and size, with integer components.

Enums

Capability	The OpenGL drawing capabilities that can be enabled or disabled.
DataType	The different OpenGL data types.
DrawingMode	The primitive drawing modes for drawing raw vertex data.
GLError	The various possible OpenGL errors.
GLFramebufferError	The possible framebuffer-incomplete errors.

Constants

BLEND	Blend newly-computed fragment colors with the current values in the color buffer.
BYTE	A signed 8-bit byte.
COLOR_BUFFER_BIT	The color buffer, which stores color information for each fragment (or pixel).
CULL_FACE	Cull polygons, based on their winding in window coordinates.
DEPTH_BUFFER_BIT	The depth buffer, which stores distance information for each fragment when depth testing is enabled.
DEPTH_TEST	Perform a depth test for each fragment, only drawing fragments that are not obscured by other geometry. Also updates the depth buffer appropriately.
DITHER	Dither color components or indices.
FIXED	A signed 32-bit, fixed-point number in 16.16 form.
FLOAT	A 32-bit, IEEE floating-point number.
LINES	Draw each pair of vertices as individual line segments.
LINE_LOOP	Draw a self-connected line segment, where each vertex is connected to the next, and the last vertex connects to the first.
LINE_STRIP	Draw a connected line segment, where each vertex is connected to the next. The first and last vertex are treated as the start and end points.
POINTS	Draw each vertex as a single point.
POLYGON_OFFSET_FILL	When filling a polygon, add an offset to each fragment's depth value.
SAMPLE_ALPHA_TO_COVERAGE	When multisampling, use the alpha value from the sample location.
SAMPLE_COVERAGE	When multisampling, use the preset sample coverage value as the alpha value.
SCISSCOR_TEST	Only draw fragments within the scissor rectangle.
SHORT	A signed 16-bit short.
STENCIL_BUFFER_BIT	The stencil buffer, which stores information about which fragments should be kept or discarded when stencil testing is enabled.
STENCIL_TEST	Perform a stencil test for each fragment, only drawing fragments that pass the currently-set stencil operation. Also updates the stencil buffer appropriately.
TRIANGLES	Draw each group of three vertices as a triangle.
TRIANGLE_FAN	Draw the vertices as a triangle fan. The first vertex, v1 is the fan's 'center'. Vertices v2 and v3 form the first triangle with the center, v1. Then vertices v3, v4, and v1 form the next triangle, then vertices v4, v5, and v1, and so on.
TRIANGLE_STRIP	Draw the vertices as a strip of triangles. The first three vertices form the first triangle, then the next vertex plus the previous two vertices form the next triangle, and so on. For example, vertices v1, v2, and v3 form the first triangle, then vertices v2, v3, and v4 form the next, and so on.
UNSIGNED_BYTE	An unsigned 8-bit byte.
UNSIGNED_SHORT	An unsigned 16-bit short.
