gldrawarrays

问题 I am activating the texture just before the object to draw. But the texture is showing on both objects. Why is that so? Should I unbind the texture before the first object to draw? - I tried with glDisable and glBindTexture but it did not help. Here my code: @Override public void onDrawFrame(GL10 gl) { GLES20.glClear(GL10.GL_COLOR_BUFFER_BIT); synchronized (camerObject) { surfaceTextureCamera.updateTexImage(); cameraUpdate = false; } vertexBuffer.position(0); GLES20.glVertexAttribPointer

问题 I'm working on a game in java using lwjgl and it's OpenGL implementation. Never had any problems until I exchanged it with a colleague who uses NVIDIA instead of AMD, and suddenly it crashes on a line that works on AMD but it only crashes at that point in the code. That is the weardest part because I use the same method to create the VBOs from .obj-files. I even tried it with the same file but still at that point it crashes on all other occasion not. Could it be maybe a wrong set flag or

问题 I am trying to follow [this][1] simple tutorial, but I am getting the following error upon reaching 'glDrawArrays': Unhandled exception at 0x03D7598E (nvoglv32.dll) in openGLTest.exe: 0xC0000005: Access violation reading location 0x00000000. void createMesh(void) { float* vertices = new float[18];// Amount of vertices vertices[0] = -0.5; vertices[1] = -0.5; vertices[2] = 0.0; // Bottom left corner vertices[3] = -0.5; vertices[4] = 0.5; vertices[5] = 0.0; // Top left corner vertices[6] = 0.5;

问题 I'm following a tutorial on creating a Game Engine in Java using OpenGL. I'm trying to render a triangle on the screen. Everything is running fine and I can change the background color but the triangle won't show. I've also tried running the code provided as part of the tutorial series and it still doesn't work.
