ResourceFactory

ResourceFactory is the factory class responsible for creating all low-level objects such as a native Texture, Sampler, GraphicsPipeline, among other things.

Once you have the GraphicsContext instance, you can use it to access 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, buffers, etc.) are represented by abstract classes, and ResourceFactory allows you to create them in the same way for all the supported APIs. For example, a ResourceFactory of DX11GraphicsContext will always create DX11 graphics resources (DX11Texture, DX11Buffer, and so on).

• Texture
• Sampler
• Framebuffer
• Shader
• QueryHeap
