finite_render_create_color_blend_state

The finite_render_create_color_blend_state function creates a Vulkan VkPipelineColorBlendStateCreateInfo from a FiniteRenderColorBlendInfo and optional custom attachment.

VkPipelineColorBlendStateCreateInfo finite_render_create_color_blend_state(
    FiniteRender *render,
    VkPipelineColorBlendAttachmentState *att,
    FiniteRenderColorBlendInfo *blend
);

Parameters

Type	Description
`FiniteRender *render`	The FiniteRender instance used to manage pipeline creation.
`VkPipelineColorBlendAttachmentState *att`	Optional pointer to a single attachment to override the default attachments. Can be `NULL`.
`FiniteRenderColorBlendInfo *blend`	Pointer to the color blend info describing attachments, logic operations, and blend constants.

Code Example

FiniteRenderColorBlendAttachmentInfo att_info = {
    .blendEnable = true,
    .srcColorBlendFactor = VK_BLEND_FACTOR_SRC_ALPHA,
    .dstColorBlendFactor = VK_BLEND_FACTOR_ONE_MINUS_SRC_ALPHA,
    .colorBlendOp = VK_BLEND_OP_ADD,
    .srcAlphaBlendFactor = VK_BLEND_FACTOR_ONE,
    .dstAlphaBlendFactor = VK_BLEND_FACTOR_ZERO,
    .alphaBlendOp = VK_BLEND_OP_ADD,
    .colorWriteMask = VK_COLOR_COMPONENT_R_BIT | VK_COLOR_COMPONENT_G_BIT | VK_COLOR_COMPONENT_B_BIT | VK_COLOR_COMPONENT_A_BIT
};

VkPipelineColorBlendAttachmentState attachment = finite_render_create_color_blend_attachment(&att_info);

FiniteRenderColorBlendInfo blend_info = {
    .flags = 0,
    .logicOpEnable = false,
    .logicOp = VK_LOGIC_OP_COPY,
    ._attachments = 1,
    .attachments = &attachment,
    .blendConstants = {0.0f, 0.0f, 0.0f, 0.0f}
};

VkPipelineColorBlendStateCreateInfo blendState = finite_render_create_color_blend_state(myRender, &attachment, &blend_info);

Standard Usage

render and blend must not be NULL.

If att is NULL, the function uses the _attachments array in blend.
