Module gl

Contains OpenGL helper functions (to compile / link shaders), VirtualGlDriver for unit testing

Structs

• FragmentShaderCompileError
• GlShader
• GlShaderLinkError
• Texture
  OpenGL texture, use ReadOnlyWindow::create_texture to create a texture
• TextureFlags
• Uniform
• VertexArrayObject
• VertexAttribute
• VertexBuffer
• VertexLayout
  Describes the vertex layout and offsets
• VertexShaderCompileError
• VirtualGlDriver
  Virtual OpenGL “driver”, that simply stores all the OpenGL calls and can replay them at a later stage.

Enums

• GlApiVersion
• GlShaderCompileError
• GlShaderCreateError
• IndexBufferFormat
• UniformType
• VertexAttributeType

Traits

• VertexLayoutDescription

Functions

• get_opengl_texture
• gl_textures_clear_opengl_cache
  Destroys all textures, usually done before destroying the OpenGL context
• gl_textures_remove_active_pipeline
• gl_textures_remove_epochs_from_pipeline
  Destroys all textures from the pipeline pipeline_id where the texture is older than the given epoch.
• insert_into_active_gl_textures
  Inserts a new texture into the OpenGL texture cache, returns a new image ID for the inserted texture

Type Aliases

• GLint
• GLuint
  Typedef for an OpenGL handle
