I have finished reworking the ground mesh for now. The result is truer to the topography of Bexar (San Antonio) in 1836. The area is larger, the river and acequia’s are more accurate and I added new features like the dam. Here is a test render of the bird’s eye view similar to the overview in George Nelson’s book. There are no textures and the buildings have not been accurately placed yet.
