ResourceFactory

ResourceFactory is the factory class responsible to create all low-level objects like a native Texture, Sampler, GraphicsPipeline among other things...

Once you have the GraphicsContext instance you can use it to access to the ResourceFactory and start creating Low-Level objects. In this example, to create a VertexBuffer object:

var vertexBufferDescription = 
    new BufferDescription((uint)Unsafe.SizeOf<VertexPositionNormalTexture>() * (uint)vertexData.Length, BufferFlags.VertexBuffer, ResourceUsage.Default);

var vertexBuffer = this.graphicsContext.Factory.CreateBuffer(vertexData, ref vertexBufferDescription);

All the common Low-Level objects (textures, buffer, ...) are represented by abstract classes, and ResourceFactory allows you to create them in the same way for all the supported APIs. So, for example, a ResourceFactory of DX11GraphicsContext always will create DX11 graphics resources (DX11Texture, DX11Buffer and so on).

Objects

The complete list of objects that you can create using the ResourceFactory are:

• Buffer
• Texture
• Sampler
• Framebuffer
• Shader
• QueryHeap
• ResourceLayout
• GraphicsPipeline
• ComputePipeline
• RayTracingPipeline
• ResourceSet
• CommandQueue
• CommandBuffer
