WebApr 17, 2024 · The GL_FRAGMENT_PRECISION_HIGH macro should only be defined when the "highp" precision modifier would be valid to use in the fragment shader (so either GLES or GLSL >= 1.30). However, some drivers (nvidia) define it even when the shader will not accept "highp", leading to shader compilation errors. WebMar 22, 2000 · GLUT is designed for constructing small to medium sized OpenGL programs. While GLUT is well-suited to learning OpenGL and developing simple OpenGL applications, GLUT is not a full-featured toolkit so large applications requiring sophisticated user interfaces are better off using native window system toolkits like Motif.
