The tools that I used are:
Now with that many bricks, it takes forever to generate an image, so at first I generated "preview" quality images where the number of rays traced is reduced, and shadows are missing. I don't like how dark the shadows are, so I'll probably play around with the lighting eventually. In the case of "the completed tower" view, I actually prefer the preview image!
|Under construction: Just the first level||22K gif|
|The completed tower||37K gif||24K gif|
|The view from inside the walls||24K gif||19K gif|
|Looking down from above||45K gif||54K gif|
|The view from outside||26K gif||22K gif|
|Another view from outside||19K gif||15K gif|
I decided to play around with different colors. Here's one of the above images, this time with three different color schemes. When Using grey, I randomly threw in some dark grey, black, and white bricks to give it some texture.
|yellow||26K gif||22K gif|
|grey||24K gif||24K gif|
|random||42K gif||43K gif|
If you're curious, there are 5584 bricks in the final product, which includes the walls and four towers (each a rotated clone of the original). Most notably, there are 2380 1x4 bricks and 2148 2x4 bricks.
Besides adding the main gate, I would like to make a movie by generating numerous frames, each with a slightly different view, simulating a minifig's journey through the castle.
I would also like to add a number of defending knights, commoners, horses, and scenery. Unfortunately, L3G0lib doesn't currently include any knight pieces, and Ben and Jer aren't releasing their models.
