@Michael_Geary You can use up to 4096 float3s in an array within a custom code node. Set output as CMOT float3, input as x.
const float3 pointcloud[4096]={{1234.5678,1234.5678,1234.5678},…{1234.5678,1234.5678,1234.5678}};
return pointcloud[x];
just make sure you have plenty of newlines in the data or it will fail with a source line too long error.
I have been looking into a way of automating the image creation from data using CanvasRenderTarget2Ds. Shouldn’t be too much of a stretch to extend it to multiple render targets to increase precision. I’ll post something soon.
