Speedtest: Blender 3D 32bit vs 64bit

Michiel — Mon, 27 Jul 2009 13:18:05 +0000

This post is mainly for the blender users, using windows. Blender is an open-source 3d editor which can be downloaded from www.blender3d.org. Even for windows, there are 2 versions of Blender3D. The 32bit version, which comes as an installer and the 64 bit version, which comes as a zipped package. The 64bit is adapted to serve 64bit computers more, and most new systems now are 64bit. But does the 64bit version really have differences in rendering and baking performance?

IOR – Index of Refraction

Michiel — Thu, 09 Apr 2009 11:29:17 +0000

When using a 3D programma, and especially using transparant materials, and index of refreaction is used. In Blender 3D, the open source 3D package, an Index of Refraction can be set up when using ray transparancy, and this is also possible in other 3D packages. To achieve a realistic result, knowing the right refraction indexes is very useful. We see an example of refraction in the image on the left, but what exactly is transparancy, and what Refraction indexes do common materials have?

The Best HDRI Maps and Textures

Texture & HDRI Sites Compared:

As a 2d and/or 3d artist, it is assumable that you use a wide range of resources. We are talking here about shapes, textures, brushes, and HDRI Maps. You can use textures from pictures that were taken by your own, or textures from dvd’s you can buy but many use the internet. Yep, that’s right, the internet. But where do we find them?. Here we will look up a few of those sites, that are providing HDRI-maps ore textures, and a short description of each site is given. First, for who textures are relatively new, textures and HDRI-Maps are explained in short. On the bottom a short list of all websites is shown.
