Example 1 with Shader

use of org.sunflow.core.Shader in project joons-renderer by joonhyublee.

the class Hair method prepareShadingState.

@Override
public void prepareShadingState(ShadingState state) {
    state.init();
    Instance i = state.getInstance();
    state.getRay().getPoint(state.getPoint());
    Ray r = state.getRay();
    Shader s = i.getShader(0);
    state.setShader(s != null ? s : this);
    int primID = state.getPrimitiveID();
    int hair = primID / numSegments;
    int line = primID % numSegments;
    int vRoot = hair * 3 * (numSegments + 1);
    int v0 = vRoot + line * 3;
    // tangent vector
    Vector3 v = getTangent(line, v0, state.getV());
    v = state.transformVectorObjectToWorld(v);
    state.setBasis(OrthoNormalBasis.makeFromWV(v, new Vector3(-r.dx, -r.dy, -r.dz)));
    state.getBasis().swapVW();
    // normal
    state.getNormal().set(0, 0, 1);
    state.getBasis().transform(state.getNormal());
    state.getGeoNormal().set(state.getNormal());
