D3DPRASTERCAPS_ Values
Use with the dwRasterCaps field of the d3dFindDeviceSearch class.
- D3DPRASTERCAPS_DITHER
- The device can dither to improve color resolution.
- D3DPRASTERCAPS_FOGTABLE
- The device calculates the fog value by referring to a lookup table containing fog values that are indexed to the depth of a given pixel.
- D3DPRASTERCAPS_FOGVERTEX
- The device calculates the fog value during the lighting operation, places the value into the alpha component of the D3DCOLOR_ value given for the specular color in the lpOut field, and interpolates the fog value during rasterization.
- D3DPRASTERCAPS_PAT
- The driver can perform patterned drawing (lines or fills with D3DRENDERSTATE_LINEPATTERN or one of the D3DRENDERSTATE_STIPPLEPATTERN render states) for the primitive being queried.
- D3DPRASTERCAPS_ROP2
- The device can support raster operations other than R2_COPYPEN.
- D3DPRASTERCAPS_STIPPLE
- The device can stipple polygons to simulate translucency.
- D3DPRASTERCAPS_SUBPIXEL
- The device performs subpixel placement of z, color, and texture data, rather than working with the nearest integer pixel coordinate. This helps avoid bleed-through due to z imprecision, and jitter of color and texture values for pixels. Note that there is no corresponding state that can be enabled and disabled; the device either performs subpixel placement or it does not, and this bit is present only so that the Direct3D client will be better able to determine what the rendering quality will be.
- D3DPRASTERCAPS_SUBPIXELX
- The device is subpixel accurate along the x-axis only and is clamped to an integer y-axis scanline. For information about subpixel accuracy, see D3DPRASTERCAPS_SUBPIXEL.
- D3DPRASTERCAPS_XOR
- The device can support XOR operations.
- D3DPRASTERCAPS_ZTEST
- The device can perform z-test operations. This effectively renders a primitive and indicates whether any z pixels would have been rendered.
