cone-1.irmf

Here is a unit cone.

/*{
  irmf: "1.0",
  materials: ["PLA"],
  max: [1,1,0.5],
  min: [-1,-1,-0.5],
  units: "mm",
}*/

float cone(in vec3 xyz) {
  // Trivially reject above and below the cone.
  if (xyz.z < 0.0 || xyz.z > 1.0) { return 0.0; }
  
  // Calculate the new size based on the height.
  float zsize = mix(1.0, 0.0, xyz.z);
  float r = length(xyz.xy);
  
  if (r > zsize) { return 0.0; }
  
  return 1.0;
}

void mainModel4(out vec4 materials, in vec3 xyz) {
  xyz.z += 0.5;
  materials[0] = cone(xyz);
}

• Try loading cone-1.irmf now in the experimental IRMF editor!

• Use irmf-slicer to generate an STL or voxel approximation.
