Members
Member name | Description | |
---|---|---|
![]() |
Add | Adds the components of the second argument to the first argument.
SRGBA = Arg1 + Arg2 |
![]() |
AddSigned | Adds the components of the arguments with a -0.5 bias, making the effective range of values -0.5 through 0.5.
SRGBA = Arg1 + Arg2 -0.5 |
![]() |
AddSigned2X | Adds the components of the arguments with a -0.5 bias and shifts the products 1 bit to the left.
SRGBA = (Arg1 + Arg2 -0.5) << 1 |
![]() |
AddSmooth | Adds the first and second arguments, then subtracts their product from the sum.
SRGBA = Arg1 + Arg2 - Arg1 * Arg2 |
![]() |
BlendCurrentAlpha | Performs linear blending on the current texture stage, using the alpha taken from the previous texture stage.
SRGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha) |
![]() |
BlendDiffuseAlpha | Performs linear blending on the current texture stage, using the interpolated alpha from each vertex.
SRGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha) |
![]() |
BlendFactorAlpha | Performs linear blending on the current texture stage, using a scalar alpha set with the TextureFactor property for a RenderStateManager.
SRGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha) |
![]() |
BlendTextureAlpha | Performs linear blending on the current texture stage, using the interpolated alpha from each vertex.
SRGBA = Arg1 * (Alpha) + Arg2 * (1 - Alpha) |
![]() |
BlendTextureAlphaPM | Performs linear blending on the current texture stage that uses a premultiplied alpha.
SRGBA = Arg1 + Arg2 * (1 - Alpha) |
![]() |
Disable | Disables output from the texture stage and all stages with a higher index. To disable texture mapping, set this flag as the color operation for the first texture stage (stage 0). Alpha operations cannot be disabled when color operations are enabled. Setting the alpha operation to Disable when color blending is enabled causes undefined behavior. |
![]() |
DotProduct3 | Modulates the components of each argument as signed components, adds their products, and replicates the sum to all color channels, including alpha. This operation is supported for color and alpha operations.
SRGBA = (Arg1R * Arg2R + Arg1G * Arg2G + Arg1B * Arg2B) |
![]() |
Lerp | Performs linear interpolation between the second and third source arguments by a proportion specified in the first source argument.
SRGBA = (Arg1) * Arg2 + (1 - Arg1) * Arg3. |
![]() |
Modulate | Multiplies the components of the arguments.
SRGBA = Arg1 * Arg2 |
![]() |
Modulate2X | Multiplies the components of the arguments, then shifts the products 1 bit to the left (effectively multiplying them by 2) for brightening.
SRGBA = (Arg1 * Arg2) << 1 |
![]() |
Modulate4X | Multiplies the components of the arguments, then shifts the products 2 bits to the left (effectively multiplying them by 4) for brightening.
SRGBA = (Arg1 * Arg2) << 2 |
![]() |
ModulateAlphaAddColor | Modulates the color of the second argument using the alpha of the first argument, then adds the result to argument one. This operation is supported only by using the ColorOperation property of a TextureStateManager.
SRGBA = Arg1RGB + Arg1A * Arg2RGB |
![]() |
ModulateColorAddAlpha | Modulates the arguments, then adds the alpha of the first argument. This operation is supported only by using the ColorOperation property of a TextureStateManager.
SRGBA = Arg1RGB * Arg2RGB + Arg1A |
![]() |
ModulateInvAlphaAddColor | Similar to ModulateAlphaAddColor, but uses the inverse of the alpha of the first argument. This operation is supported only by using the ColorOperation property of a TextureStateManager.
SRGBA = (1 - Arg1A) * Arg2RGB + Arg1RGB |
![]() |
ModulateInvColorAddAlpha | Similar to ModulateColorAddAlpha, but uses the inverse of the color of the first argument. This operation is supported only by using the ColorOperation property of a TextureStateManager.
SRGBA = (1 - Arg1RGB) * Arg2RGB + Arg1A |
![]() |
MultiplyAdd | Performs a multiply-accumulate operation, in which this field multiplies the last two arguments, adds them to the remaining input/source argument, and places that into the result.
SRGBA = Arg1 + Arg2 *Arg3 |
![]() |
PreModulate | This flag is set in stage n, the output of which is arg1. If stage n + 1 contains a texture, then the Current value of a TextureArgument is premultiplied by that texture. |
![]() |
SelectArg1 | Uses this texture stage's first color or alpha argument, unmodified, as the output. This operation affects the color and alpha arguments used with the ColorOperation and AlphaOperation properties of a TextureStateManager, respectively.
SRGBA = Arg1 |
![]() |
SelectArg2 | Uses this texture stage's second color or alpha argument, unmodified, as the output. This operation affects the color and alpha arguments used with the ColorOperation and AlphaOperation properties of a TextureStateManager, respectively.
SRGBA = Arg2 |
![]() |
Subtract | Subtracts the components of the second argument from those of the first argument.
SRGBA = Arg1 - Arg2 |
