Poor performance drawing quads
|
Hello,
This is revisit from http://www.gamedev.net/community/forums/topic.asp?topic_id=576359.
I implemented my own mechanism for rendering quads, lines, points and point sprites using a material system as a replacement for D3DXSprite. The perf... |

Help with bitmap font rendering
|
Hello,
I implemented custom font rendering in my engine using bitmapped fonts (loaded at runtime from true type or raster font). Most of it is working well, however I am getting visual artifacts concerning the horizontal and vertical spacing of dr... |

Pure Device w/State Manager slower than Non Pure w/o one!
|
Hello,
My engine uses an Effects system and has a state manager on pure device, just like the State Manager sample in the SDK. Because my states are cached, I found that the state blocks that Effect uses internally to save and restore state c... |

Custom batching: wrong materials applied
|
Hello,
I wrote my own batching system to replace D3DXSprite because I wanted more flexibility. Recently I started getting this problem - when I drop my in game console and start typing, some of the triangles rendered later in a batch than the cons... |

Wrote batching system to replace D3DXSprite, now poor performance
|
Hello,
I needed some extra functionality for rendering objects in my 2D app, so I decided to write my own class to handle batching. Unlike D3DXSprite, it can handle objects that use different Effects with different parameters, various geometry typ... |

Point Sprites with Effects
|
I am rendering a point list with a D3DXEffect. Vertex declaration is XYZ+PSIZE, effect vertex shader is null, and pixel shader takes float2 texcoord: TEXCOORD0.
When I sample using that texcoord in the pixel shader (and just return the result), I... |

D3DPT_LINELIST: lines are 1 pixel off

Hello,
I wrote a function to render lines with D3D9 device - it takes a list of points and a list of 16-bit indexes, then debug version calls DrawPrimitiveUP with appropriate parameters (release version does batching). Lines appear (and I am using... |

GetGlyphOutline - different black box for GGO_METRICS and _BITMAP

Hello,
I haven't been able to find an answer to the issue I am having with GetGlyphOutline. When getting info for the same character, passing GGO_METRICS flag returns one black box size, and passing GGO_GRAY8_BITMAP returns another black box... |

Game Development Comic

Hello all,
I wanted to start a comic about game development for several years now, and I finally got to the stage of roughing out characters. There will probably be like half a year before I get the first few episodes out, but some is better than... |

DirectSound buffer with generated data

Hello,
My friend recently asked me to write a program that generates square waves of configurable frequency. I used DirectSound before for playing static buffers without streaming, but adjustable frequency play, as I understand, would require havi... |

Video Settings of my Game
|
I think the texture detail setting is supposed to reduce texture memory usage, which means you physically have to load smaller resolution textures. SetLOD only controls the mip level used from a texture with mip levels already loaded. In order t... |

Poor performance drawing quads
|
I looked at Instancing sample on the SDK. I have one question: if I store the positions, colors and tex coords of my quads in shader constants as arrays, then what should the verts themselves contain? Should I have each vert contain just th... |

Poor performance drawing quads
|
I am using D3D9, I believe instancing is D3D10 or D3D9c only feature?
The major part of the slow-down is in rendering text. Somehow I doubt that sending 500 or so draw calls is going to be faster than sending 2 draw calls with 250 quads each.... |

Help with bitmap font rendering
|
For anyone interested, the problem was resolved. Turns out GetGlyphOutline returns different values when it's called with GGO_METRICS versus GGO_BITMAP flags. GGO_METRICS is used to get only metrics and GGO_BITMAP is used to retrieve the bitmap... |

Help with bitmap font rendering

Thank you for your replies.
I fixed the horizontal inter-letter spacing, that works fine now.
The spacing of characters from the baseline is still incorrect. I am using exactly the same formula as what you posted. With font Courier New point si... |

Custom batching: wrong materials applied

[EDIT]
Updating for anyone who might later get the same problem. It appears the cause of this error is two-fold.
The reason the problem was happening only in Debug mode is because vertex buffers get cleared to 0s by the runtime for validat... |

Damn,composing's hard!

Music composition actually has a ton of rules - scales (major, natural minor, etc), degrees, modes (ionian, dorian, phrygian, etc), chords and chord progressions, knowing what key you are playing in, intervals (major 2nd, minor 3rd, perfect 4th, etc)... |

Small file transfers?

File transfer from server is really easy to do, if you are already running an HTTP server. I wrote a simple file download routine just last week:
1. Include wininet.h and link to wininet.lib
2. Call InternetOpen to initialize WinInet library, sav... |
