That wasn't something that I did plan, it just happened, like it happens to a person of going through different periods in his music listening habits.

This is taken from basically straight ahead at around 0,0. This screenshot was taken with back face culling on! We are just showing the lines here so you can clearly see the geometry. It is up to you whether you implement your terrain using face nomals or vertex normals.

You should consider efficiency when constructing and drawing the terrain. Trees The levels include trees at different points on the terrain.

Your second task is to draw the trees at the specified locations. In the screenshots, the trees are drawn with two separate textured meshes: For the base part of the assignment, you only need to have a tree that is a single textured mesh. We have provided a PLY file of a tree that you can use.

The point is that they are placeable 3d models on the terrain. Note that the level descriptions only specify the x,z location of the tree. You will need to use the terrain data to calculate the altitude of the tree and draw it appropriately.

Trees are not guaranteed to be positioned at grid points, so you will need to interpolate altitude values if a tree is in the middle of a triangle. Camera You should implement a 3D camera which moves around the scene using the arrow keys: The up arrow moves forward The down arrow moves backward The left arrow turns left The right arrow turns right.

The camera should move up and down following the terrain. So if you move it forward up a hill, the camera should move up the hill. Sunlight Your world should be rendered using Phong shading. The vector represents the direction to the source of the light.

You can base it off one of the preexisting shaders if you wish. Note that the shader will also need to support texturing. You will need to decide for yourself what are the appropriate other properties for the light and the appropriate material properties for the surfaces that will reflect it.

Final milestone end of week 12 Avatar Add an avatar and make the camera follow behind the avatar in a 3rd person view. You should being able to switch from 1st person with no avatar to 3rd person with the avatar by pressing a key of your choice. For the base part the avatar does not need to be a complex model a bunny is okbut it does need to be textured.

Road The level include roads. Each road is described as a 2D Bezier curve.

I have provided a function for you which calculates the x,z location of points along the road. You will need to to use this function to extrude a road which follows this curve, with the width specified in the constructor.a dialect of lisp using turtle graphics famous for teaching kids.
