Hello, if you have any need, please feel free to consult us, this is my wechat: wx91due

Installation steps for your laptop:

If you want to use the directx texture tool you can install the old directx sdk from jun 2010: old DirectX SDK has some good tools that we will use. (when installing, it might give you some warnings, you can ignore those)

You will be running premake to generate visual studio solutions. They will be for older visual studio (vs2015) but you can open them in 2022 version just fine.

Install cygwin

Run cygwin once, it will create the user folder. In cygwin user folder, in .bashrc file (in my case C:\cygwin\home\Artem\.bashrc) , append these lines to make cygwin handle files with windows line endings properly(more info):

export SHELLOPTS

set -o igncr

Install Autodesk Maya(use autodesk and free student license)

[Task 1] Soldier #1 - Choose Between Waypoints

Add ability to specify more than one next waypoint (up to 3) in waypoint script. Then in code choose one randomly whenever soldier chooses next waypoint. This should make Soldier #1 have a more randomized movement instead of circling the car.

Task 1 alternative: because we don’t have Maya working yet, what you can do is instead use existing level and randomly choose either next waypoint specified , or waypoint specified after next waypoint, effectively skipping one waypoint. This will still give a randomized choice of where soldier goes next.

[Task 2] Soldier #2 - Tracking New Object

Create a new object type called Target (similar to what is done in first two tutorials). Add ability to SoldierNPC to turn to the target and play shooting animation (SoldierNPCAnimationSM::STAND_SHOOT). Trigger this ability on the soldier that goes into idle (not the soldier that keeps running around the car). Note, it is acceptable to just repurpose solider object as a target, by adding some parameters so that on code side you could use imrod mesh instead of solider skinned mesh.

The target should be moving close to soldier. Doesn't really matter what movement pattern it is (can be circling around soldier) as long as it moves and the soldier keeps turning towards it. Use imrod mesh for the Target object.

Task 2 Alternative: we have sample code to create imrod mesh straight from code, you can use that instead of going through process of creating new object through Maya. So you would just hardcode creating of new object. You can also create SoldierNPC from code directly, if you want. Creating a simple mesh object and give it some motion is much easier than creating a soldier npc and changing which mesh it issues. We will discuss in class.

So end result will look like this:

The soldier moves to the point, stops, starts shooting at the target object .

For A2, when creating a target, it is enough to just debug draw a locator. Just like we draw waypoints you can just debug draw text that says “target” and moves around.Then the solider needs to aim at that.

Your submission will be a video recording of the results working and text file/commentary on what was done.A2

In this homework you are going to concentrate on math and optimization. Currently all renderable objects (s.a. meshes, skinned meshes) are always submitted to graphics pipeline for rendering. This is quite inefficient considering that objects could be outside of camera view and could be completely ignored.For this assignment, you will create bounding volumes for objects and perform a culling test with camera view frustum. So if you have a bounding volume around a mesh, and it does not intersect with camera frustum, it can be completely ignored. You will do it for static meshes that are loaded from files.

You will create Axis Aligned Bounding Box around meshes. Note, AABB is axis aligned in local mesh space, but can take any orientation when mesh is moved around in the world based on orientation of SceneNode. You need to find where the mesh point information is stored and analyze all the points to generate AABB

You will need to add helper functions to render a box and in debug renderer, similar to how transforms are already being rendered for soldiers. This way, we will be able to see how well the volumes have been generated. You might need to increase static limits of number of lines that the renderer can handle.

3) Creating Frustum Plane Equations

4) Testing bounding volumes

Finally, you will need to use bounding volumes to test with camera view frustum and dismiss the mesh instances that are not intersecting with camera view frustum.

I added code to spawn 100 imrods in ClientCharacterControlGame::initGame(), look for spawnALotOfMeshes and set it to true to enable.Rendering all of them causes framerate drop. However with bounding volume check, framerate goes higher. In case you have a monster machine that does not take performance hit rendering 100 imrods, make it a thousand imrods. So if your code works framerate should be almost the same as running game without ever spawning imrods.

The final version of the assignment in your video should have the planes generated with a little smaller fov so that we can see objects popping off before they are fully off the screen.

Your submission will be a video with description of how everything is working. Keep a copy of your workspace with the solution in case we ask to upload it to perforce. Make sure to generate planes with a smaller fov so we can see objects popping off.
