Support / JPCT Hello World
« on: June 11, 2006, 10:21:15 pm »
Thanks for your reply.

For testing I'm just using a JFrame and putting everything in paint for simplicity (except for the TextureManager because I guess there's no point adding the same texture repeatedly).

I don't need any animation at this point, just a single rendered image which later will be generated on a server with no video card (hence the need for a software renderer).

I've added the w.buildAllObjects(); as you suggest, but I'm still not getting anything.

I'll take a look at your maze example and see if I can extract the essentials.

Regards, Redstop.

JPCT looks like just what I need, but I'm having trouble putting together a minimal sample to explore. The two sample programs go far beyond what I need and I'd rather start from a "Hello World" sample and build up. Can anyone point me to a simple example that shows just a primitive (eg. a box) using the software renderer?

Here's my code, which doesn't work:

Code: [Select]

// this is done once, just in case shapes must have a texture
// must they?
TextureManager tm = TextureManager.getInstance();
tm.addTexture("default", tm.getDummyTexture()); // should be white

// here's the paint:
public void paint(Graphics g)
  Dimension sz = getSize();
  World w = new World();

  // just copied from the sample
  w.setAmbientLight(25, 30, 30);

  // these just copied from the car example
  // no idea if ambient light is sufficient
  w.addLight(new SimpleVector(0, -150, 0), 25, 22, 19);
  w.addLight(new SimpleVector(-1000, -150, 1000), 22, 5, 4);
  w.addLight(new SimpleVector(1000, -150, -1000), 4, 2, 22);

  Object3D box = Primitives.getBox(100, 100);
  box.setOrigin(new SimpleVector(200,200,200));
  box.setVisibility(true); // is this the default?
  box.setTexture("default"); // will it take dummy texture otherwise?

  FrameBuffer buffer=new FrameBuffer(sz.width, sz.height,  
  // I found staring at an empty black screen
  // after each attempt at getting this to work too depressing

All I get is a blank (yellow) screen.
What I want to see is a white box on a yellow background.

Any help appreciated. Thanks, Redstop.
