- Implementing different noise and blending functions
- Thinking of more creative mesh deformations
- (Personal) recreate a cute character I enjoy
Since the project guidelines was to make a fireball, I decided to make my favorite ball of fire: Calcifer, from Howl's Moving Castle!
I also wanted to explore more stylistic rendering/shader choices, like limited frame rates.
On the site, you will have customization with the following controls:
- Speed: Multiplier for time; modifies all time-reliant functions.
- Intensity: The strength of the flame; Calcifer will be a blue lump when intensity is low, and lively when intensity is high!
- Anger: Makes calcifer's expression angry! What did you do to him??
- Color: Calcifer's base color!
Noise functions:
- Used worley noise as the backing lava cell shaping & protrusions
- FBM-based perturbation near the top of the flame
- FBM-based flicker
Toolbox functions:
- Floor function to limit time buffering for reduced frame rate effect.
- Triangle wave for the base of Calcifer's blinking loop
- Squaring to make Calcifer's blinking loop easen in
- Use of smoothstep and mix functions to blend the seam transition from top of flame to bottom of flame.
- Simple sine-based grow/shrinking + in-sync glow.
