Edit: 2 years later
The engine eventually powered the game that was called Project: Rhapsody in Laser (RiL). Screenshots of its development (check the date modified on the screenshots to get a chronogical order) are at http://cade.mooo.com/rils... |

[Resolved][MDX]Planar reflection, HLSL

Fixed, in the shader,
OUT.texProj = mul(projTex, IN.position);
should have been
OUT.texProj = mul(IN.position, projTex);
Hey everyone,
I'm having a bit of a problem with planar reflection in a HLSL shader. I'm not exactly sure what is... |

[Resolved]Running an OpenGL app creates files named ilog*.txt
|
Whenever I run an OpenGL app, files named ilog*.txt appear in the same folder as the exe, which contain nothing. Does anyone know why this happens?

[Resolved][MDX]Small problem, updating vertexbuffer of a mesh created by Mesh.Sphere

Hey everyone, I've got one small problem with the D3DX mesh class. I usually use my own mesh formats, but for the occlusion culling of lights, I am using meshes.
My code is
Public CullMesh As Direct3D.Mesh
CullMesh = Mesh.Sphere(... |

Creating a deformed sphere
|
Hey everyone,
In my engine, the final check (after octree and frustum) if a point light is visible, is to occlusion query it's light mesh (Sphere with the radius of the point light). But if it has a large radius, and is in a corridoor, the actual... |

Using octrees for rendering - Removing non-visible cubes
|
Hey everyone,
In my engine, currently I use octrees for rendering the scene. My current method is to traverse the tree and render the node if it
a) is visible
and
b) has no children
I define a node as visible if it passes either test
a) The... |

Simulating rigid bodies floating in fluid, 2d

Hey everyone,
I was thinking of setting up "fluid volumes" in my 2d sidescrolling engine (A region defined as containing fluid). I was wondering, given a rigid body in a fluid volume, distance from surface, pressure and density at that point, how... |

Yet another parallax mapping demo
|
Your demo looks nice. Since OpenGL and DirectX do not have the same "tangent space", I think your bump maps were designed for OpenGL matrices. Try reversing the direction of your tangent and/or binormals. |

Deferred shading is okay, I guess, nothing really special about it to me. |

For stained shadow mapping, I render depth to the alpha channel and modulatve alpha translucent surfaces to the RGB channels. If the card doesnt support floating point textures, I use 2 RTs instead. |

Thanks for your complements, guys :)

Forward vs. Deferred Rendering

Schrompf, in my engine, I write out the ambient term as a pass, before doing the lighting passes.
I don't think deferred shading is only good for non-shadow casting lights, since I use it both with lights that cast and do not cast shadows, th... |

Strange HLSL variable issue

Look at the output which the fxc compiler generates, before and after changing that line of code, and see if there's a difference.
If your not using the fxc directly, but creating the shader in your app through an Effect, use D3DXDisassembleEffect... |

What is the Filter at D3DXCreateTextureFromFileEx for?

The SamplerState specifies how the texture is filtered when it renders. The parameter to D3DXCreateTextureFromFileEx specifies how the texture is filtered after it is created but before it is returned, but this only happens if the texture is res... |

The non-transparent surfaces, are just parallax mapping with normal mapping. The surfaces sample the shadow map and the stained shadow map. Since transparent surfaces are done after the non-transparent geometry has been rendered, they can sample the... |
