DESCRIPTION

The RTC_FORMAT_UINT/2/3/4 format are used to specify that data buffers store unsigned integers, or unsigned integer vectors of size 2,3 or 4. This format has typically to get used when specifying index buffers, e.g. RTC_FORMAT_UINT3 for triangle meshes.

The RTC_FORMAT_FLOAT/2/3/4... format are used to specify that data buffers store single precision floating point values, or vectors there of (size 2,3,4, etc.). This format is typcally used to specify to format of vertex buffers, e.g. the RTC_FORMAT_FLOAT3 type for vertex buffers of triangle meshes.

The RTC_FORMAT_FLOAT3X4_ROW_MAJOR and RTC_FORMAT_FLOAT3X4_COLUMN_MAJOR formats, specify a 3x4 floating point matrix layed out either row major or column major. The RTC_FORMAT_FLOAT4X4_ROW_MAJOR and RTC_FORMAT_FLOAT4X4_COLUMN_MAJOR formats, specify a 4x4 floating point matrix layed out either row major or column major. These matrix formats are used in the [rtcSetGeometryTransform] function in order to set a transformation matrix for geometries.

The RTC_FORMAT_GRID is a special data format used to specify grid primitives of layout RTCGrid when creating grid geometries (see [RTC_GEOMETRY_TYPE_GRID]).
