BeginScene..EndScene without Present [SOLVED]

Hi all,
I'm trying to do some offline renderization (for radiosity generation using the GPU) and my simplified code looks like this:
procedure GenerateRadiosity;
begin
// Set up device states
PrepareRenderStates;
// Prepare ou... |

Redundant transformations on a frame
|
I'm doing some optimizations on my engine, and I tested the same scene with different polygon counts. That's how I found that the vertex count is a bottleneck on my rendering implementation.
This is the steps of a single frame with two l... |

UltraShadow on ATI?
|
Hello everybody,
Yesterday I implemented Hardware Shadow Mapping (taking advantage of the nVidia's UltraShadow technology) on my 3D engine. Luckily it was easier than I expected :) I tested on my GeForce 6800 and it ran ok.
But today... |

Zenith 3D Engine

Hello everybody!
I hope that someone remember my previous 3D engine, v3D (It was on Image of the day a few months ago). The project continued to grow and I turned the engine into Zenith 3D Engine. These are the main features:
Integrated d... |

HDR and Multisample
|
Hi all :)
Is there any way to enable multisample in a HDR scene? If I'm rendering the scene in a A16B16G16R16F RT texture, is there any way to do it with multisample enabled?
I read somewhere that you can create a render target using IDirect3D... |

3D lines without ID3DXLine
|
Hello everyone!
I'm working on a rope object and I need to draw lines without using the ID3DXLine.DrawTransform method (because it doesn't fill the depth buffer with the Z values).
I read in this forum that the best way to do this is drawin... |

I am happy to show you the latest features of my 3D engine for Delphi (v3D VCL), I hope you like it :)
All scenes are rendered using Blooming, Tone Mapping, Color Correction, Depth of Field, LightMaps (using a built-in lightmap generator), Varian... |

Ray/Box collision: Intersection point?

Hello,
I am working on several raytracing algorithms for lightmap computations. I implemented intersections at vertex-level for shadow casting without problems.
But this process is very expensive, so I want to test the intersections at b... |

Planar mapping and normals

Hi everybody :) Excuse my English...
I'm implementing LightMaps in my 3D engine using the planar mapping algorithm.
I will explain it for whoever is interested.
Steps (for each polygon):
1- Obtain the polygon normal and choose the greate... |

Questions about Lightmaps
|
Hello everyone!
I'm reading and reviewing concepts to begin using LightMaps in my 3D engine(www.v3d-vcl.com.ar).
I have a few questions about it and I couldn't find a concrete answer, so here I go:
- For each lightmap, do I have to waste hal... |

lightmap GENERATION CODE
|
I used the first link you posted to build my lightmap generator. But I did it in Pascal, if you think you could use my Pascal code I can paste it for you.

Or you can use an approach like this one.

.X file format is a nightmare

If you want to use a software like 3D Studio and load those models with the LoadModelX() I have an algorithm that converts the .3DS format to the .X format (but it's in Pascal):

Question about shadow mapping
|
ATI also does the depth comparison automatically when you use tex2Dproj() on some hardware. I remember the ATI HD 2400+ doing it. |

Weird "rings" appearing for spotlights
|
That looks like the expected precision for a X8R8G8B8 buffer on some cards. The same scene textured should hide those "rings" to the viewer. |

light masks implementation like CryEngine

This question also applies to the shadow generation. Yes, you have to render the scene once per light to generate the shadow map. But when filling the buffer with the shadows, do you store them in separate chan... |

light masks implementation like CryEngine

Quote:Original post by jcabeleiraBut in that case, shading and shadowing aren't truly separated. You still have to write 2 versions of the same shader, one that samples the light mask and another that doesn't.

light masks implementation like CryEngine
|
Quote:Original post by maya18222
1. Render whole scene as depth only write to depth buffer
2. Create shadowmaps for each light, (could be a 1 four channel rendertarget for 4 lights, or 2 four channel rendertargets for 8 lights etc etc)
3. Cre... |

light masks implementation like CryEngine

I recently implemented the same technique in my engine, so my rendering pipeline went from:
- render geometry for ambient term and simple lighting
- for each shadowmapped light N
- - render geometry for light N's shadowmap
- - render geometry f... |

Tactical MMOG - second pre-alpha image

Great visuals! It reminds me of the Source Engine but with better AO and lightmaps. Congrats! |
