Alphas in Zbrush

After working with wireframes i wanted to see how possible it was to use patternated negative space. to wrap a pattern around an object and use its negative ares within the shape.

Many programmes can do this but i found a few useful tutorials for zbrush so i started there.

In zbrush you need to create an alpha. which is a black and white or greyscale picture. then once imported to zbrush, the white and black ares determine what is extruded and what is not. or maybe how much the extrusion is depending on the shade of grey.

Im still working on this..

In more basic forms i used the highlight selection tool to draw some radial patterns on a sphere.

I thought it made an interesting piece. its a pretty solid model to print i think aswell.

Next I went on to play with basic scribbles as alphas, i made in photoshop these were super basic ( and lazy) and then extruded them on different models.

i got some interesting results, but they do interrupt the stability of the model because of what ive drawn.

I also used the stock face model for fun to see what would happen.

next I used one of the stock textures see what i could create on a basic sphere and plane.

i think they look really interesting and definitely something i want to return to.
