Struct BasicModifier 

pub struct BasicModifier<G: GaussianPod, S = NoSelection> {
    pub transform_flags_buffer: TransformFlagsBuffer,
    pub basic_color_modifiers_buffer: BasicColorModifiersBuffer,
    pub rot_scale_buffer: RotScaleBuffer,
    pub modifier: BasicModifierBundle<G, S>,
}

A struct to handle basic modifier.

This modifier holds a BasicModifierBundle along with necessary buffers, and applies the basic modifier.

Fields

transform_flags_buffer: TransformFlagsBuffer

basic_color_modifiers_buffer: BasicColorModifiersBuffer

rot_scale_buffer: RotScaleBuffer

modifier: BasicModifierBundle<G, S>

impl<G: GaussianPod> BasicModifier<G>

pub fn new( device: &Device, gaussians_buffer: &GaussiansBuffer<G>, model_transform_buffer: &ModelTransformBuffer, gaussian_transform_buffer: &GaussianTransformBuffer, ) -> Self

Create a new basic modifier.
