  1. OK, I found the problem, I made a little mistake in initialize lighting.But thanks for reply
  2. Hi I have got a problem with lights in my OpenGL apllication. I have a models with textures and normals. [attachment=4605:no light no material 2.png] When I turn light on, it's works fine. gl.glEnable(GL10.GL_LIGHTING); //other lights parameters [attachment=4603:light no material 2.png] But I also wanted to use color insted useing material, so I turn ColorMaterial gl.glEnable(GL10.GL_COLOR_MATERIAL); and there is a problem because "light effect" dissapeared, Why ? [attachment=4604:light_and_material 2.png] There are model's screen without lighting [attachment=4605:no light no material 2.png] As you can see model without lighting and model with lighting but with ColorMaterial turned on, are equals Can anyone help me ? Or anybody can give good example with lighting and ColorMaterial turned on? Thanks in advance
  3. Hi! I would like to draw simple cube using glDrawElements, glTexCoordPointer . There is part of my code glBindTexture(GL_TEXTURE_2D, texture[0]); glEnableClientState( GL_VERTEX_ARRAY ); // Enable Vertex Arrays glEnableClientState( GL_TEXTURE_COORD_ARRAY ); // Enable Texture Coord Arrays float vertices[] = { 1.0f, 0.0f, -1.0f, //0 index 1.0f, 0.0f, 1.0f, //1 -1.0f,0.0f, 1.0f, //2 -1.0f, 0.0f,-1.0f, //3 1.0f, 1.0f, -1.0f, //4 1.0f, 1.0f, 1.0f, //5 -1.0f,1.0f, 1.0f, //6 -1.0f, 1.0f, -1.0f, //7 }; short indices[] = { 0, 1, 2, 0, 2, 3, 0, 4, 5, 0, 5, 1, }; float texture[] = { 1, 0, 1, 1, 0, 1, 0, 0, //... I repeat these 4 coordinate 2 times 1, 0, 1, 1, 0, 1, 0, 0,}; glVertexPointer( 3, GL_FLOAT, 0, vertices ); // Set The Vertex Pointer To Our Vertex Data glTexCoordPointer( 2, GL_FLOAT, 0, texture ); // Set The Vertex Pointer To Our TexCoord Data glDrawElements(GL_TRIANGLES, 12, GL_UNSIGNED_SHORT, indices); The vertices and indices are show below: [attachment=2315:cube_gamedev.png] I try render bottom and right face of this cube with texture, but only bottom face is textured, as you can see below [attachment=2316:cube_textire.png] Why only bottom face is textured ? I gave texture coordinates for 2 faces. Also if I give more textures coordinates it won't work. Is there another method to draw textured cube using glDrawElements ?
  4. so there is no way to use glDrawElements ? I'd like avoid glVertex3f and glTexCoord2f and VBO to make my code a bit compatible with OpenGL ES, so glDrawArray is the only way ?
  5. Hi! I would like to changing fullscreen window in my DX9 Application while running. Normally to set fullscreen mode I turn it on by "Windowed = FALSE" in D3DPRESENT_PARAMETERS struct. But I did it while initialize my D3Ddevice. How I can switching between fullscreen mode while running application ? Again creating D3Device with opposite value in "Windowsed" ? Thanks in advance.
