  1. PODrawing normals in LWJGL messes with lighting
    text
    copied!<p>My issue is fairly straightforward: Drawing normals in LWJGL causes the light source to only apply to the model until it is manually updated after initialization. Here's the lighting initialization:</p> <pre><code>static Vector3f lightPosition = new Vector3f(-500f, -100f, 500f); GL11.glEnable(GL11.GL_LIGHTING); GL11.glEnable(GL11.GL_LIGHT0); GL11.glLightModel(GL11.GL_LIGHT_MODEL_AMBIENT, asFloatBuffer(new float[]{0.05f, 0.05f, 0.05f, 1f})); GL11.glLight(GL11.GL_LIGHT0, GL11.GL_DIFFUSE, asFloatBuffer(new float[]{1.5f, 1.5f, 1.5f, 1f})); </code></pre> <p>And here's my code for drawing the normals (loaded from the Standford Bunny model):</p> <pre><code>for (Face f : bunnyModel.faces){ Vector3f n1 = bunnyModel.normals.get((int)f.normal.x - 1); GL11.glNormal3f(n1.x, n1.y, n1.z); Vector3f v1 = bunnyModel.vertices.get((int)f.vertex.x - 1); GL11.glVertex3f(v1.x, v1.y, v1.z); Vector3f n2 = bunnyModel.normals.get((int)f.normal.y - 1); GL11.glNormal3f(n2.x, n2.y, n2.z); Vector3f v2 = bunnyModel.vertices.get((int)f.vertex.y - 1); GL11.glVertex3f(v2.x, v2.y, v2.z); Vector3f n3 = bunnyModel.normals.get((int)f.normal.z - 1); GL11.glNormal3f(n3.x, n3.y, n3.z); Vector3f v3 = bunnyModel.vertices.get((int)f.vertex.z - 1); GL11.glVertex3f(v3.x, v3.y, v3.z); } </code></pre> <p>What am I doing wrong here? When I disable normals, lighting works fine on everything but the model. But when I enable them, the bunny receives light, but no other surfaces do.</p>
