A function that could be used to convert ToxicLibs meshes to PShape:
PShape toxicToPShapeSmooth(final Mesh3D m) {
m.computeVertexNormals();
Collection<Face> triangles = m.getFaces();
shp = createShape();
shp.setStroke(false);
shp.beginShape(PConstants.TRIANGLES);
shp.textureMode(PConstants.NORMAL);
for (final Face t : triangles) {
shp.normal(t.a.normal.x, t.a.normal.y, t.a.normal.z);
shp.vertex(t.a.x, t.a.y, t.a.z, t.uvA.x, t.uvA.y);
shp.normal(t.b.normal.x, t.b.normal.y, t.b.normal.z);
shp.vertex(t.b.x, t.b.y, t.b.z, t.uvB.x, t.uvB.y);
shp.normal(t.c.normal.x, t.c.normal.y, t.c.normal.z);
shp.vertex(t.c.x, t.c.y, t.c.z, t.uvC.x, t.uvC.y);
}
shp.endShape();
shp.setSpecular(0xFFFFFFFF);
shp.setShininess(50);
}
