wireframe display with shaders

psykolio

Hello! I'm practicing with shaders these days, and found this great ressource: http://www.creativeapplications.net/processing/geometry-textures-shaders-processing-tutorial/

I'd like to achieve the effect you see in the beginning of the video and here: http://www.creativeapplications.net/wp-content/uploads/2013/05/AmnonOwed-GTS-GLSL_SphereDisplacement01.jpg, displaying the texture of a shape only on his wireframe structure (this effect is not included in the sources of the tutorial).

Any idea?

Processing's inner architecture, especially related to OpenGL, is constantly changing.

Right now, you could use the following code.

// add global import
import javax.media.opengl.GL2;

// place before shader & shape calls in draw()
GL2 gl = ((PJOGL)beginPGL()).gl.getGL2();
gl.glPolygonMode( GL2.GL_FRONT_AND_BACK, GL2.GL_LINE );

// place after shader & shape calls in draw()
gl.glPolygonMode( GL2.GL_FRONT_AND_BACK, GL2.GL_FILL );
endPGL();

Hi There. I was looking for the same effect, but on video capture.
I want to display the video.start(); only on his wireframe. Can anyone help me?
