New Colorpicker

Minor update - added a new color picker to replace the former palette

Specular support for the Editor

First result including specular created in the editor

Color & Normal Compression Result

The screenshot below shows the result; includes specular lighting.
Octree: 115 MB , 2.88 bytes / voxel (including specular, glow, and more components),
Resolution : 4096x4096x4096 voxels

Using zip for storing the octree on disk reduces the size to ~1.44 bytes/voxel
( This includes color, normal, position and LOD data )

Comparison to common compression methods:

Color compression, DXT1: 0.5 byte / pixel
Normal compression, 3dc: 1 byte / pixel (only tangent space, no arbitrary normals!)
Linear octree: ~2.275 bit / voxel (for a surface, ~4 of 8 bit/node are used)

For CRUNCH, it provides ~1 bit/pixel for color and ~2 bit / pixel for normals.

Example with 4 different specular power settings

Color & Normal Compression

The new version uses 24 bit colors with color & normal compression. It achieves a 1:9 compression ratio compared to uncompressed storage. Speed impact is about 5-10%.

Raytrace Shadows and Smoothing Filter

Added a simple smoothing filter and raycasted shadows.

Skybox

Update: Skybox and more octree levels added

Block based level editing

First step for the level editor.
