Fields
cull_face: CullFace
front_face_order: FrontFaceOrder
depth_test: Comparison
depth_write: bool
depth_write_offset: Option<(f32, f32)>
color_blend: Option<BlendState>
Color (RGB) blend function. If None - blending will be disabled for this pipeline. Usual use case to get alpha-blending:
PipelineParams {
color_blend: Some(BlendState::new(
Equation::Add,
BlendFactor::Value(BlendValue::SourceAlpha),
BlendFactor::OneMinusValue(BlendValue::SourceAlpha))
),
..Default::default()
};
alpha_blend: Option<BlendState>
Alpha blend function. If None - alpha will be blended with same equation than RGB colors. One of possible separate alpha channel blend settings is to avoid blending with WebGl background. On webgl canvas’s resulting alpha channel will be used to blend the whole canvas background. To avoid modifying only alpha channel, but keep usual transparency:
PipelineParams {
color_blend: Some(BlendState::new(
Equation::Add,
BlendFactor::Value(BlendValue::SourceAlpha),
BlendFactor::OneMinusValue(BlendValue::SourceAlpha))
),
alpha_blend: Some(BlendState::new(
Equation::Add,
BlendFactor::Zero,
BlendFactor::One)
),
..Default::default()
};
The same results may be achieved with ColorMask(true, true, true, false)
stencil_test: Option<StencilState>
color_write: (bool, bool, bool, bool)
