4.1.3.20. Type
This module provides classes to handle OpenGL Data Types.
It gives access to the following functions to set and get uniform values:
- glGetUniform{f|i|ui|d}v
- glUniform{1|2|3|4}{f|i|ui}
- glUniform{1|2|3|4}{f|i|ui}v
- glUniformMatrix{2|3|4|2x3|3x2|2x4|4x2|3x4|4x3}fv
- glProgramUniform{1|2|3|4}{f|i|ui}
- glProgramUniform{1|2|3|4}{f|i|ui}v
- glProgramUniformMatrix{2|3|4|2x3|3x2|2x4|4x2|3x4|4x3}fv
