Description

template<EBlurSamples KERNEL>
class nap::BlurShader< KERNEL >

Gaussian blur shader that samples a Texture2D in a specified direction. For a full gaussian blur, call this shader twice, setting up a material that samples horizontally (direction = {1.0, 0.0}) and vertically (direction = {0.0, 1.0}).

The gaussianblur shader exposes the following shader variables:

uniform UBO
{
    vec2 textureSize;   // The size of 'colorTexture', used to pre-calculate sampling coordinates in vertex shader
    vec2 direction;     // The sampling direction
} ubo;

uniform sampler2D colorTexture; // The input color texture to sample from

◆ init()

bool init ( utility::ErrorState & errorState )

overridevirtual

Cross compiles the font GLSL shader code to SPIR-V, creates the shader module and parses all the uniforms and samplers.

Parameters

errorState contains the error if initialization fails.

Returns: if initialization succeeded.

Reimplemented from Object.
