Is it开发者_如何学JAVA possible to render all of the OpenGL ES things into a normal allocated buffer instead of the framebuffer:
I have a class in my Java layer which implement Renderer. Inside this class I have a bitmap which I want to pass to JNI layer. JNI layer would be responsible for displaying bitmap by using OpenGL. Can

Here is my GL init code: gl.glEnable(GL10.GL_TEXTURE_2D); gl.glShadeModel(GL10.GL_SMOOTH); gl.glEnable(GL10.GL_BLEND);
If I have a mesh (such as a cube with 6 faces, each consisting individually of 4 vertices, totaling 24 vertices) and I want to apply a different texture to each face, how would I do this? Currently I
I\'m having a bit of a problem with开发者_如何学JAVA this. I wanted to make a push button. However, I don\'t know how to use the Button class with OpenGL. I am not using the \"R\" class within Java in
Like many 3d graphical programs, I have a bunch of objects that have their own model coordinates (from -1 to 1 in x, y, and z axis).Then, I have a matrix that takes it from model coordinates to world
I\'m trying to detect the opengl object under the cursor... I have read it referred to as picking. Here is my code:
I am trying to set a .png file as my background in OpenGL, with the hopes of drawing more objects on top of it. I have an image that is a 320x480 RGB image. I setup my vertices, as follows:
