#gamedev progress:

I can now draw on scrolls :)

#gamedev progress:

• reworked book model to fix issues with normals when book was opened
• refactored input handling from event based to having a big struct of the input state passed to the update function
• implemented the first interaction with the world. Books can now be picked up and placed back into shelves

#rust #dev

#

#gamedev progress:

• Static geometry (walls, floor ceiling) is split up into smaller chunks to allow culling
  • Implementation: generated geometry is loaded into a BVH with a larger leaf size (256). The geometry of each leaf is converted to an entity.
  • Culling via distance to the player.
• Added player physics. No longer clipping through walls and shelves. Not stable enough yet.
• Reworked ray casting system to handle animated objects correctly.
• Player can now click on books to open them.

#gamedev progress:

• small refactoring of OcTree to simply change the intersection test function during construction. This allows to choose between accurate or fast functions.
• OcTree is working now. Only included the static geometry at the moment. Can now ray cast into the scene.

#octree #rust

#

#gamedev progress:

• currently working on an OcTree implementation
• implemented GJK Algorithm for collision detection.
  • AlexanderFabisch/distance3d was a great reference. I had some missing details which lead to infinite loops.

#

#gamedev progress:

• reworked animation system to allow drawing instanced animated objects
• each instance has an animation time
• animation matrices are generated as frames

The normals of the animated mesh still look wrong. Not yet sure why.

#gamedev progress:

• Procedural book shelves are now used within the level, replacing the fixed model.
• Started implementation of a world state object as "array of fat structs"
• Implemented an algorithm to find free space within a shelf for a new book.

#rust

#

#gamedev progress:

Implemented a procedural version of the book shelves. The geometry is created by simple inset and extrusion operations on quads.
