Member Function Documentation

◆ reflect()

template<typename Processor >

static constexpr void CeresEngine::GPUBlendDescriptor::reflect ( Processor && RTTI )

inlinestaticconstexpr

Executes the given processor for every field of the struct.

Parameters

RTTI	The processor to be ran for every field.

Member Data Documentation

◆ alphaToCoverageEnabled

bool CeresEngine::GPUBlendDescriptor::alphaToCoverageEnabled = false

Specifies whether to use alpha-to-coverage as a multi-sampling technique when setting a pixel to a render target.

By default disabled. This is useful when multi-sampling is enabled and alpha tests are implemented in a fragment shader (e.g. to render fences, plants, or other transparent geometries).

◆ blendFactor

Vector4f CeresEngine::GPUBlendDescriptor::blendFactor = {0.0f, 0.0f, 0.0f, 0.0f}

Specifies the blending color factor.

By default (0, 0, 0, 0).

Remarks: This is only used if any blending operations of any blending target is either BlendOp::BlendFactor or BlendOp::InverseBlendFactor.

◆ independentBlendEnabled

bool CeresEngine::GPUBlendDescriptor::independentBlendEnabled = false

Specifies whether to enable independent blending in simultaneous color attachments.

By default false.

Remarks: If this is true, each color attachment has its own blending configuration described in the targets array. Otherwise, each color attachment uses the blending configuration described only by the first entry of the targets array, i.e. targets[0] and all remaining entries targets[1..7] are ignored.

◆ logicOp

GPULogicOp CeresEngine::GPUBlendDescriptor::logicOp = GPULogicOp::Disabled

Specifies the logic fragment operation.

By default LogicOp::Disabled.

Remarks: Logic pixel operations can not be used in combination with color and alpha blending. Therefore, if this is not LogicOp::Disabled, independentBlendEnabled must be false and blendEnabled of the first target must be false as well. If logic fragment operations are not supported by the renderer, this must be LogicOp::Disabled.

◆ targets

Array<GPUBlendTargetDescriptor, 8> CeresEngine::GPUBlendDescriptor::targets

Render-target blend states for the respective color attachments.

A maximum of 8 targets is supported.

Remarks: If independentBlendEnabled is set to false, only the first entry is used, i.e. targets[0] and all remaining entries targets[1..7] are ignored.
