Hi there,
I`ve been playing with the blue nodes again. So I thought I put my experiments in this old thread again to have it all
- especially the useful comments - in one place. Anyway...
Right now I am trying to understand what the "Get" nodes all do.
It is quite often not really clear to me how to use these nodes in the context of a scene. Let alone how to hook them up in a network,
how to use the data they provide and what kind of data they actually provide (like scalar, vector or whathaveyou).
It would be nice to have some rudimentary example networks for (in my case actually most) blue nodes.
First one I tried is the "Get Camera Position".
The Wiki says: "Provides the current position of the main camera in world space, independent of current shading context."
So what to do with this?
Since it is the main cameras position I thought that an animated camera would be the best way to visualize this.
The (at least my) default scene has a Simple Shape Shader connected to the Mask input of the Fractal Terrain node.
The picture of the network shows how I fed the Get Camera Position to the Simple Shape Shader.
The Multiply by Constant Scalar helps to magnify the cameras position values to values big enough to be noticable (x 1000 in this case).
The animation file:
At the start of the movie the Camera is far away from the Simple Shape Shaders position.
What happens when you get closer and decrease the distance between Camera and Simple Shape Shader is what is shown in the animation.
Nice and smooth shape shifting.
