I'm trying to teach myself more about 3d in max, mainly OpenGL, so I'm attempting to copy techniques I've seen. The first is this: http://tasarix.com/v10-pages/7pwrs.html.
To me it looks like it's drawn from the base up gradually, it changes colour, grows in size and orbit as it goes. I can do the last three things but it's the trail or line it leaves that has me stuck. I thought maybe a line with points being added to a sketch but a line is flat, it doesn't have volume, any ideas?
Second question, can't find a visual to explain this, but it's a texture effect I've seen somewhere where the texture on a 3d shape isn't wrapped around the shape but is flat on it as if the shape is a window through which the texture is seen. Pretty sure this is easy, just can't remember how to do it.
Thanks in advance
