4 OpenGL Vectors🔗ℹ

 (require sgl/gl-vectors) package: sgl

The sgl/gl-vectors module supports OpenGL programming with cvectors. In this document and in the error messages, a “gl-vector” is just a cvector, while a “gl-type-vector” is a cvector with an appropriate type. Use the sgl/gl-vectors module vectors instead of a Racket cvector directly, because they are specialized to handle the OpenGL types correctly.
