§ Vertex Array Object State

1. † The $i$th attribute defaults to a value of $i$.

§ Vertex Array Data (not in vertex array objects)

§ Buffer Object State

1. † This state may be queried with \glr{GetBufferParameteriv}, in which case values greater than or equal to $2^{31}$ will be clamped to $2^{31}-1$.

§ Transformation State

§ Rasterization

§ Implementation Dependent Values

1. † These limits are tied to the values of \glc{MAX_TEXTURE_SIZE} (for width/height) and \glc{MAX_SAMPLES} (for samples) respectively.

§ Implementation Dependent Values (cont.)

1. † These queries return the maximum no. of samples for all internal formats required to support multisampled rendering.
2. ‡ “ULP” means “Units in the Last Place” or “Unit of Least Precision”.

§ Implementation Dependent Values (cont.)

1. † The value of {\small\tt TEXTURE_BUFFER_OFFSET_ALIGNMENT} is the maximum allowed, not the minimum.

§ Implementation Dependent Version and Extension Support

§ Implementation Dependent Vertex Shader Limits

§ Implementation Dependent Tessellation Shader Limits

§ Implementation Dependent Tessellation Shader Limits (cont.)

§ Implementation Dependent Geometry Shader Limits

§ Implementation Dependent Fragment Shader Limits

§ Implementation Dependent Compute Shader Limits

1. † The minimum value is \glc{MAX_COMPUTE_UNIFORM_BLOCKS} $\times$ \glc{MAX_UNIFORM_BLOCK_SIZE} / 4 + \glc{MAX_COMPUTE_UNIFORM_COMPONENTS}

§ Implementation Dependent Aggregate Shader Limits

1. † The value of {\small\tt UNIFORM_BUFFER_OFFSET_ALIGNMENT} is the maximum allowed, not the minimum.
2. ‡ The minimum value for each stage is {\small\tt MAX_{\em{stage}}_UNIFORM_BLOCKS} $\times$ {\small\tt MAX_UNIFORM_BLOCK_SIZE / 4} + {\small\tt MAX_{\em{stage}}_UNIFORM_COMPONENTS}. The limit is totalled for all uniform variables in all uniform blocks, including the default.

§ Implementation Dependent Aggregate Shader Limits (cont.)

§ Implementation Dependent Aggregate Shader Limits (cont.)

1. † The value of {\small\tt SHADER_STORAGE_BUFFER_OFFSET_ALIGNMENT} is the maximum allowed, not the minimum.

§ Debug Output State

1. † The initial value of \glc{DEBUG_OUTPUT} is \glc{TRUE} in a debug context and \glc{FALSE} in a non-debug context.

§ Implementation Dependent Debug Output State

§ Implementation Dependent Transform Feedback Limits

§ Framebuffer Dependent Values

1. † This state is queried from the currently bound read framebuffer, rather than the draw framebuffer. $n$ is the value of \glc{SAMPLES}.
