Depending on its type, each command consumes a variable number of coordinates from the vertex coordinate array. There are two categories of commands: ones that cause a path segment to be drawn, and ones that affect how path is rendered. When a path is drawn, the command array is processed sequentially. Path segments are specified using a command array and a vertex coordinate array. Stroking corresponds to generating the fragments that lie within a region defined by sweeping a straight-line pen along the path. Filling corresponds to generating the fragments that lie within the interior of the path. Use cases for this extension include acceleration of vector graphics content and text rendering.Ī path is defined as a number of segments, representing either straight lines, or quadratic or cubic Bezier curves, and can be either filled or stroked.

This extension adds functionality to render planar Bezier paths. Written based on the wording of the OpenGL 2.0 Specification.

Limited stride support for texture updates Note that 32-bit floating point textures are accepted, but are converted to 16-bit floating point textures internally, and thus use of this extension is not recommended.ġ6-bit (1 sign bit, 5 exponent bits, 10 mantissa bits)
