CommonFilters but now you can add your own!!!
It appends the code you've added to CommonFilters internal shader string before CommonFilter compiles the shader and adds its own code.
This version of common filters adds the methods add_filter, load_filter, add_uniform, remove_uniform, remove_filter, add_shader_input, and add_shader_inputs.
add_filter(name: str, string: str, order:int = None) takes in the name of the filter (whatever you want it to be), a string and optionally the order where it should be.
load_filter(name: str, file: str, order:int = None) loads a file from disk and then see add_filter.
add_uniform(string: str) adds a uniform(s). Note you can just write type uniform_name instead of uniform type uniform_name, (ex. float
remove_uniform(index: int) removes uniform(s) from the stored uniform list.
remove_filter(name: str, inputs: list = None, uniforms: list = None) removes the filter by name and optionally any shader inputs (by name) or uniforms (this must match the value of the string in add_uniform).
add_shader_inputs(inputs: dict) updates shader inputs
add_shader_input(name: str, value) updates shader input
Keep in mind I didn't port anything to glsl so you still need to use Nvidia's CG.
from CommonFilters import CommonFilters
from direct.showbase.ShowBase import ShowBase
s = ShowBase()
p = s.loader.load_model("panda")
p.reparent_to(s.render)
c = CommonFilters(s.win, s.cam)
c.setBlurSharpen(0.5)
c.add_uniform("float raise_amount")
c.add_shader_inputs({"raise_amount": 0.5})
c.add_filter("""o_color += 0.5 * raise_amount;""", 0)
c.add_uniform("float increase_red")
c.add_shader_input("increase_red", 0.5})
c.add_filter("""o_color.r += increase_red;""", 0)
s.run()Should look like this
I'll probably add support for reording the builtin filters as well but that'll be later.
