Picture modeled off of

Model

Did this in raw povray/kpovmodeler. Trying to reimplement in blender, but blender lacks good CSG, so it's even harder to do there(as you can see, I heavily use CSG, thus it takes forever to render). Can't find a suitable rough metal texture, and too lazy to code one myself. Brick texture impossible to align on pyramid. The lighting was made horrible to hide the ugliness

Slightly better texturing(cheated using bump mapping, shell part's texture made by modelling scratches in Blender, then gimping the rendered image.). Now using area lights. The texture on the pyramid now using UV-mapping to align the bricks. Still lacks detail (painful to do without modeler, and Blender, without CSG to cut holes in things, just doesn't cut it.

At least it looks recognizable...kinda.

Considering how hard it is to work with POVray and how limited free modellers can be, good work.

It's looking fairly good. You know I actually think the ship would look better, while being far more sensible, if the structure around the pyramid was all solid. But if you intent on making a replica that's of course not an option.

Would actually be possible to model in blender too, instead of povray if it were solid. The cutouts require CSG or uber-1337 modeling skills, of which the first gets screwed up with anything remotely complex (Has anyone tried k3d? Blender is too oriented toward organic and animation stuff).

[rant]
Raw povray is a pain in the ass- previewing anything takes a while to render on a PII-450, and installing pvm-povray probably won't help much if all you have is a PII-266 windows box and a PII-450-linux box. It would still be less powerful than what some of the people on the board complaining about slow computers have.

Example of bad hardware would be modeling an M1 tank, using an image stucsurfacek to the background as a guide. RIVA TNT2 has poor 2D OpenGL acceleration, so that isn't usable, Blender takes up whole screen, so can't put it in seperate window, and print quality being horrible off of a 10 yr old B&W BJ-230 with the wrong drivers (correct omni drivers too difficult to install on linux, and even then probably poor quality, which is why I haven't sent files upstairs to print using the windows drivers back to down here). Blender project appears unhealty financially, so...
[/rant]

I'm giving up on this model, at least until I explore other modeling alternatives. I'll work on more solid things. Need to add details to the three holes around the pyramid, and thin out the sections. Bump mapping should look deeper and scratches larger, surface less shiny, this part is easy. School is starting, so I don't have time to burn on this stuff though.
