Resource limitation constants.

#define Value Description
D3D10_REQ_MIP_LEVELS 14 Maximum number of mipmap levels a texture resource may have.
D3D10_REQ_RESOURCE_SIZE_IN_MEGABYTES 128 Maximum possible size of a resource in megabytes. Apps can create resources bigger than the maximum resource size on some graphics hardware. However, we recommend that apps keep resources smaller than the maximum resource size to get the maximum amount of compatibility across graphics vendors. The runtime only guarantees that allocations within the maximum resource size are supported by all Direct3D 10 hardware.
D3D10_REQ_TEXTURE1D_ARRAY_AXIS_DIMENSION 512 Maximum array size of a 1D texture array.
D3D10_REQ_TEXTURE2D_ARRAY_AXIS_DIMENSION 512 Maximum array size of a 2D texture array.
D3D10_REQ_TEXTURE1D_U_DIMENSION 8192 Maximum width of a 1D texture.
D3D10_REQ_TEXTURE2D_U_OR_V_DIMENSION 8192 Maximum width and height of a 2D texture.
D3D10_REQ_TEXTURE3D_U_V_OR_W_DIMENSION 2048 Maximum width, height, and depth of a 3D texture.
D3D10_REQ_TEXTURECUBE_DIMENSION 8192 Maximum size of a cube texture.

 

The constants are defined in D3D10.h.
