Detailed Description

OpenGL Shader Program Management.

Provides an interface for managing OpenGL/GLES2 shader programs used in GRIB data visualization:

Shader Programs:

• Colored triangle shaders for basic geometry
• 2D texture shaders for overlays and maps
• Circle shaders for particle effects
• Vector field visualization shaders

Features:

• Cross-platform shader support (OpenGL/GLES2)
• Builder pattern for shader compilation
• Viewport transformation
• Error handling and validation
• Program caching
• Uniform parameter management
