If you need your particles or points to be rendered with constant size according to your camera, in Houdini, this is what you could do. Add a UV Texture SOP. Change texture type to Perspective from Camera. Insert your Camera path. Change attribute class to Point. Add a Point Wrangle SOP. We want the scale…

Starting from the basics: SOP: surface operator, geometry network DOP: dynamic operator, dynamic network VOP: vex operator, vex builder network SHOP: shader operator, shader network CHOP: channel operator, motion/audio network COP: compositing operator, img network ROP: render operator, out network POP: particle operator, particle network Points, vertexex, primitives. Vertexes are part of a primitive. Points are the…

Remember: VDB from Polygon to create a volume from polygons. Some VEX here. VEX stands for Vector Expressions. SHIFT + R to reverse the node inputs. The full list of VEX functions is here. to declare a variable: int nameofthevariable; // create a integer variable vector nameofthevariable; // create a vector variable Fetching vector P…

Finally, we start to animate! Alt + LMB on a parameter: add keyframe Ctrl + LMB: remove keyframe To align the handle to world coordinates press M! And dynamics! On the top shelf, select Rigid Bodies. The first tab is RBD object (RBD stands for Rigid Body Dynamics). It creates an AutoDOP network, automatically generated Dynamics…
