Presentation


DXTViewer is a compressed texture viewer. These textures, mainly in DDS format (Direct Draw Surface), are commonly used in realtime 3D applications. Compressed textures leads to increased procurement efficiency, due to two major improvements which are:

  • less diskspace and video memory consumption
  • direct loading into the graphics video memory (no transformation stage required) Texture loading is dramatically increased even for high resolution images (4096x2048 for instance).

DXTViewer handles the following S3TC compression formats: DXT1, DXT3, DXT5 and ATI's 3Dc. Furthermore, DXTViewer allows to load usual image formats such as JPG, BMP, TGA, PNG or GIF. These files can be converted in compressed textures in DDS (Direct Draw Surface) or O3TC (oZone3D Texture Compression) formats. The O3TC format has the same features than DDS (S3TC DXT1,DXT5 and ATI 3Dc), is really simple to load and is not Y-reversed like the DDS See the Bump Map Compression tutorial for more information about O3TC loading.

Highlight features


  • Use of OpenGL for texture rendering
    (GL_EXT_texture_compression_s3tc / GL_ATI_texture_compression_3dc extensions)
  • Loading of *.DDS (DXT1, DXT3, DXT5 and ATI 3Dc ) format
  • Loading of *.O3TC (DXT1, DXT5 and ATI 3Dc) format
  • Loading of *.JPG, *.BMP, *.TGA, *.PNG, *.GIF, *.TIF, *.PSD formats
  • Texture Saving in *.DDS (Direct Draw Surface) and *.O3TC (oZone3D Texture Compression) with DXT1, DXT5 compression.
  • Normal-map compression: export in Swizzled-DXT5 or ATI's 3Dc compression
  • Very fast texture paning and zooming


System Requirements


  • Operating System: Windows XP SP1 or SP2
  • Processor: Pentium III or AMD Athlon and up processor - 800 MHz and up.
  • Memory: 256M RAM or higher
  • Graphics Controller: ATI Radeon 9500 and up (with the latest Catalyst drivers) or GeForce FX 5200 and up (with the latest Forceware drivers)

Version 1.1.0 of DXTViewer has been successfully tested with Windows XP SP2 and nVidia GeForce 7800GT (with Forceware 81.98) as well as ATI Radeon X800XL (with Catalyst 6.2).
