finite_render_create_generic_buffer

The finite_render_create_generic_buffer function creates a Vulkan buffer with associated memory and optionally separates vertex and index data.

bool finite_render_create_generic_buffer(FiniteRender *render, FiniteRenderBufferInfo *info, FiniteRenderMemAllocInfo *mem_info, uint64_t vertexSize, FiniteRenderReturnBuffer *rtrn)

Parameters

Type	Description
`FiniteRender *render`	The `FiniteRender` object associated with the Vulkan device.
`FiniteRenderBufferInfo *info`	Buffer creation info struct.
`FiniteRenderMemAllocInfo *mem_info`	Memory allocation info struct for selecting memory type and flags.
`uint64_t vertexSize`	Size in bytes of the vertex portion of the buffer.
`FiniteRenderReturnBuffer *rtrn`	Pointer to a struct that receives the created buffer, memory, and vertex/index offsets.

Code Example

FiniteRenderReturnBuffer buf;
FiniteRenderBufferInfo bufferInfo = {
    .next = NULL,
    .flags = 0,
    .size = 1024,
    .useFlags = VK_BUFFER_USAGE_VERTEX_BUFFER_BIT | VK_BUFFER_USAGE_INDEX_BUFFER_BIT,
    .sharing = VK_SHARING_MODE_EXCLUSIVE,
    ._fIndex = 0,
    .fIndex = NULL
};

FiniteRenderMemAllocInfo memInfo = {
    .next = NULL,
    .flags = VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT | VK_MEMORY_PROPERTY_HOST_COHERENT_BIT
};

bool result = finite_render_create_generic_buffer(myRender, &bufferInfo, &memInfo, 512, &buf);

Standard Usage

This function must have valid FiniteRender, FiniteRenderBufferInfo, and FiniteRenderMemAllocInfo structs.

vertexSize must be smaller than or equal to info->size. The remaining portion is considered index data.
