Some months ago I started using Papervision3D. I like Papervision3D, it’s a innovative open source project, and the Core Team of PV3D are challenging the performance of the Flash Player. Who know correctly this 3D rendering engine, you can make a lot of innovatives dynamics back-ends 3D, it can be a way for a very interesting innovation. I’m already begun exploring Papervision3D.

I decided to share my firsts experiments:

• Construction of a3D triangle.
  
  In this experiment I learned how to create a TriangleMesh3D, the process is simple, every point in space is an instance of the class Vertex3D, and the faces are based on these points. The way of mapping faces I’ll post later.

• My next step was to create a plane joining two triangles.
  
  Papervision3D already exists in the Plane class, but I decided to do it manually, with the goal of learning how to build instances TriangleMesh3D.

• Then I started to experiment to create 3D games,
  
  I used the Particles class to create particles at each vertex of the plane and it’s rotate around the y axis. The limitation is the very low framerate, it is necessary to optimize the code, but for a first experience was very nice. I was happy :D. To rotate and move the camera position, you can use your mouse and arrow keys

• My next experiment consisted in the construction of algebraic surfaces instanciating TriangleMesh3D class, and made my first integration with Tween Papervision3D in this experiment.
  To rotate and move the camera, you can use your mouse and arrow keys. And press the space key to change the subject.

• The experiment quoted above simply play with the depth of Vertex3D points, I make a small modification so that the x and y components follow a sine curve, and the z component of the transition point.
  Some objects are ugly, some rare, but gives an idea of what can be done with careful mathematical study of surfaces to create.

• There are many classes to create materials in Papervision3D, the basic tests that I made with Papervision3D materials used for the following types of materials:
  flatShadedMaterial
  gouraundMaterial
  phongMaterial
  cellMaterial
  envMapMaterial
  
  To view the types of materials listed above, you must re-compile the source code you must uncoment addChild methods.

• I was interested to make a small integration of sound materials.

• This example of cubes and spheres in Papervision3D was very easy to make, simply because using primitive objects.
  You can use de arrows keys to see the 3D objects.

This is my first post about Papervision3D, I’ll post frequently about this.
