示例1: CalculateLossy
public unsafe void CalculateLossy(IDeviceContext context, ITexture2D target, ITexture2D previous, ITexture2D temporalDiff, int mostDetailedMip)
{
var mipInfo = new MipInfo { MipLevel = mostDetailedMip, CoordDivisor = 1 << mostDetailedMip };
var map = context.Map(mipInfoBuffer, 0, MapType.WriteDiscard, MapFlags.None);
*(MipInfo*)map.Data = mipInfo;
context.Unmap(mipInfoBuffer, 0);
// todo: try doing everything using MostDetailedMip of SRV
context.ShaderForDispatching = computeShader;
context.ComputeStage.UniformBuffers[0] = mipInfoBuffer;
context.ComputeStage.ShaderResources[0] = previous.ViewAsShaderResource(formatId, 0, previous.MipLevels);
