Hi,
This is kind of annoying as I am not getting any errors - I am trying to load an .obj file with this simple code but all I get is a gray area. Here is the code:
- /*
- Load a scene from an .obj file as simple as it gets.
- model is the free Sponza Atrium by Marko Dabrovic:
- http://hdri.cgtechniques.com/~sponza/
- Downloads: http://hdri.cgtechniques.com/~sponza/files/
- */
- import javax.media.opengl.*;
- import processing.opengl.*;
- import objimp.*;
- float aspectRatio = 1;
- ObjImpScene scene2;
- void setup()
- {
- size( 800, 600, OPENGL );
- aspectRatio = width / (float)height;
- hint( ENABLE_OPENGL_4X_SMOOTH );
- smooth();
- frameRate( 60 );
- try
- {
- scene2 = new ObjImpScene( this );
- scene2.load( dataPath("vogel.obj"), 5 );
- // scene2.load( dataPath("spheres.obj"), .5 );
- } catch( Exception e )
- {
- println( e );
- System.exit( 0 );
- }
- }
- void draw()
- {
- float time = millis() * 0.001;
- background( 0.4*255 );
- perspective( PI*.25, aspectRatio, 1, 6000 );
- camera( 0, 3, 0, -2*cos(time*.5), sin(time)*2+3, -2*sin(time*.5), 0, 1, 0 );
- // setup light. to do correct lighting you need to set it before any world transformations
- GL _gl = ((PGraphicsOpenGL)g).beginGL();
- setupLight( _gl, new float[]{0, 15, 0}, 1 );
- ((PGraphicsOpenGL)g).endGL();
- scale( 1, -1, 1 ); // make y axis points up
- // translate( 0, -10, 0 );
- rotateY( radians(mouseX) );
- scene2.draw();
- }
- // val is 0 or 1. 0 = directional light, 1 = point light
- void setupLight( GL g, float[] pos, float val )
- {
- float[] light_emissive = { 0.0f, 0.0f, 0.0f, 1 };
- float[] light_ambient = { 0.0f, 0.0f, 0.0f, 1 };
- float[] light_diffuse = { 1.0f, 1.0f, 1.0f, 1.0f };
- float[] light_specular = { 1.0f, 1.0f, 1.0f, 1.0f };
- float[] light_position = { pos[0], pos[1], pos[2], val };
- g.glLightfv ( GL.GL_LIGHT1, GL.GL_AMBIENT, light_ambient, 0 );
- g.glLightfv ( GL.GL_LIGHT1, GL.GL_DIFFUSE, light_diffuse, 0 );
- g.glLightfv ( GL.GL_LIGHT1, GL.GL_SPECULAR, light_specular, 0 );
- g.glLightfv ( GL.GL_LIGHT1, GL.GL_POSITION, light_position, 0 );
- g.glEnable( GL.GL_LIGHT1 );
- g.glEnable( GL.GL_LIGHTING );
- g.glEnable( GL.GL_COLOR_MATERIAL );
- }
- void stop()
- {
- super.stop();
- }
And this is what Processing tells me:
Loaded OBJ from file '/Users/Caroline/Documents/Processing/MIJN PROGRAMMA/vogelobj/data/vogel.obj'
4568 vertices.
5586 normals.
2811 textures coordinates.
And as far as I know there's nothing wrong with the .obj file.
