A3 - Shader Pipeline

v0.3 - Shader Pipeline

• The engine uses a shader pipeline to draw geometry.
• Shader Editor: open your shaders or create new ones on runtime with a text editor.
• Shader Hot Reload: Editing a shader in-engine automatically compiles and applies the changes.
• Shader compile error lines and messages are shown in the editor (Console Window).
• Dynamic Shader Uniform Detection & Modification: uniform values are dynamically read from the shader and can be edited from the inspector.
• The shader editor is actually functional and can be used to create shaders and test them on runtime.
• New shaders can be applied to materials with the editor.
• Engine keeps track of loaded shaders to change between them when necessary on gameobjects materials.
• Ymir Engine's default shader ("MyShader.glsl") is applied on GameObjects that don't have any texture or any specific shader attached.
• Water Shader: Flat mesh (plane) that should simulate simple water.
  • Vertex Shader: Simple wave movement.
  • Fragment Shader: The color of the pixels changes based on its height (blue on the bottom, white on the top).

Additional functionality (Cool features!)

• Apart from the water shader, there are more shaders included (all of them created and tested on the engine itself):

Lava Shader

Rainbow Shader

Color Shader

Information about the engine and instructions available in the README.md file, inside the zip.

A2 - Engine Editor

v0.2 - Engine Editor

• The ‘Street Environment’ scene is automatically loaded at the start.
• The user is be able to use the inspector to modify a GameObject:
  • Hierarchy: delete, reparent, create empty and create children.
  • Transform: translate, rotate and scale GameObjects.
  • Camera is a component with settings that can be modified.
• GameObjects can be picked from the world using the mouse.
• All meshes use a bounding volume (AABB) and can be discarded using Frustum Culling.
• Models, meshes and textures are saved to Ymir Engine format under “Library” folder.
• Scene is serialized to a file that can be loaded.
• The user can Start / Pause / Stop the simulation and recover its original state.
• The editor has 2 windows:
  • One with the scene (Editor view).
  • Another one captured from a GameObject with a camera component (Main Game Camera).
  • Each one has its own framebuffer and the user can visualize both at the same time.
• Resource Management:
  • Assets Window that shows all user assets.
  • The user can drop/import new files. Assets window reacts properly.
  • On first use, the temporal folder Library is created and meta files are generated for each new imported asset.
  • Library can be regenerated if deleted.
  • The imported assets are saved in Library folder with Ymir Engine custom file format.

Additional functionality (Cool features!)

• There is a space skybox by default. In the folder Assets/Skybox there is more skybox textures in case you want to test several environments.
• The Assets and Library Windows have some files highlighted on blue, you can interact with them to read the contents inside the engine.
• When you select a GameObject, the shader makes an orange highlight to the mesh.
• There is an option in Inspector -> Mesh Component to turn on/off the Normal Map of the selected Mesh (done by shader).
• The Gizmo has been implemented and can be used to manage GameObjects' transformations.
• The shaders now can be loaded using a single file instead of separating Vertex Shader and Fragment Shader.
• Added Node Editor for future material editing with shaders.

Information about the engine and instructions available in the README.md file, inside the zip.

A1 - Geometry Viewer

v0.1 - Geometry Viewer

• Baker House automatically loaded at the start.
• Two models provided in FBX format with one channel diffuse texture.
• Drag&Drop of FBX files from anywhere in the Hard Drive.
• Drag&Drop of DDS/PNG files (apply the texture to the selected GameObject).
• GameObject structure, one for each loaded mesh.
• Three components available for the GameObjects: Transform, Mesh and Material.
• Unity-like camera controls.
• Editor Windows:
  • Console: Show LOGs.
  • Configuration:
    • A graph for the frames per second.
    • Configuration for variables on each module (renderer, window, input, textures).
    • Information output of memory consumption and hardware detection.
    • OpenGL configuration.
    • ...and more!
  • Hierarchy: list with all GameObjects with tree structure. The user is able to select a GameObject through this window.
  • Inspector: displays information about the components of the selected GameObject.
• About Modal Window to get info about the engine.
• Menu to load basic shapes.

Additional functionality (Cool features!)

• Early Shader Implementation for Rendering Geometry with VAO (Vertex Shader and Fragment Shader).
• Apply Transformations to Geometry with the Transform Component (Translation, Rotation and Scale).
• Custom Icon Uploaded to the Engine Executable.
• Extensive primitive library inside the engine on GameObject menu.
