Member Data Documentation

alphaArithmetic

BlendArithmetic LLGL::BlendTargetDescriptor::alphaArithmetic = BlendArithmetic::Add

Alpha blending arithmetic. By default BlendArithmetic::Add.

blendEnabled

bool LLGL::BlendTargetDescriptor::blendEnabled = false

Specifies whether blending is enabled or disabled for the respective color attachment.

colorArithmetic

BlendArithmetic LLGL::BlendTargetDescriptor::colorArithmetic = BlendArithmetic::Add

Color blending arithmetic. By default BlendArithmetic::Add.

colorMask

std::uint8_t LLGL::BlendTargetDescriptor::colorMask = LLGL::ColorMaskFlags::All

Specifies which color components are enabled for writing. By default LLGL::ColorMaskFlags::All to enable all components.

Remarks

If no pixel shader is used in the graphics pipeline, the color mask must be set to LLGL::ColorMaskFlags::Zero (or 0) to disable rasterizer output. Otherwise, the behavior is undefined.

dstAlpha

BlendOp LLGL::BlendTargetDescriptor::dstAlpha = BlendOp::InvSrcAlpha

Destination alpha blending operation. By default BlendOp::InvSrcAlpha.

Remarks

The destination alpha channel must not have a color-only blend operation.

dstColor

BlendOp LLGL::BlendTargetDescriptor::dstColor = BlendOp::InvSrcAlpha

Destination color blending operation. By default BlendOp::InvSrcAlpha.

srcAlpha

BlendOp LLGL::BlendTargetDescriptor::srcAlpha = BlendOp::SrcAlpha

Source alpha blending operation. By default BlendOp::SrcAlpha.

Remarks

The source alpha channel must not have a color-only blend operation.

srcColor

BlendOp LLGL::BlendTargetDescriptor::srcColor = BlendOp::SrcAlpha

Source color blending operation. By default BlendOp::SrcAlpha.
