Orthographic Topview on SDF?

FUSE question
2

Fuse raymarching does not yet seem to support orthographic projection.

I think I can temporarily solve this by adding the following to the setupRay function in FuseRayMarchBase.sdsl in the Fuse library.

if (Projection[2].w == 0.0) 
{
	rd = -normalize(ViewInverse[2].xyz);
	ro = mul(float4(mul(float4((uv.xy*2-1)*float2(1,-1),0,1),ProjectionInverse).xy,0,1),ViewInverse).xyz;
}
