ThePentiumGuy Posted August 18, 2004 Posted August 18, 2004 (edited) Hey, I'm trying to create a skybox. In my game, my meshes render just fine. But when I create a skybox (6 textured quads) nothing appears. - So I tried messing around with quads(loading textures onto vertex buffers and rendering). When I render my quad at 0,0,1 it appers fine. But when I render my quat at 0,0, 1.000001, it dissappears (a little exxaguration, but you know what I mean, any Z > 1, it disappears) Yes, I'm clearing my ZBuffer, and Yes, i'm setting a ZDepth of 1 D3Ddev.Clear(ClearFlags.Target Or ClearFlags.ZBuffer, Color.FromArgb(0, 0, 225), 1.0, 0) (1.0 is the max it can go). So I thought it had to do with the Projection matrix. When i set up the projection matrix: D3Ddev.Transform.Projection = Matrix.PerspectiveFovLH(System.Convert.ToSingle(Math.PI) / 4, mDisplaymode.Width / mDisplaymode.Height, 1.0F, 1000.0F) the object disappears altogether! even when the Z is set to 1. Does anyone know how to fix these problems? All i want to do is use that same projection matrix, and a matrix LookAtLH to render my meshes as well as quads. For some reason any quad with a Z > 1 disappears. Thanks Pent edit: Just to clarify: My object is centered (by default) at 0,0,0. Its height,depth,and width are 512. so the backleft coordinate is (-256,-256,-256), its far right coordinate is (256,256,256) My World is set to Identity. My View is set to: D3Ddev.Transform.View = Matrix.LookAtLH(new Vector3(0,0,0), New Vector3(0, 0, 1), New Vector3(0, 1, 0)) My Projection is set to: D3Ddev.Transform.Projection = Microsoft.DirectX.Matrix.PerspectiveFovLH(CSng(Math.PI) / 4, 800.0F / 600.0F, 0.0F, 300.0F) I created my own class (using CustomVertex.PositionTextured) I turned Culling and I can't see my box :).
