154 \qmlproperty string QtQuick.Particles::CustomParticle::vertexShader -

156 This property holds the vertex shader's GLSL source code. -

157 -

158 The default shader passes the texture coordinate along to the fragment -

159 shader as "varying highp vec2 qt_TexCoord0". -

160 -

161 To aid writing a particle vertex shader, the following GLSL code is prepended -

162 to your vertex shader: -

163 \code -

164 attribute highp vec2 qt_ParticlePos; -

165 attribute highp vec2 qt_ParticleTex; -

166 attribute highp vec4 qt_ParticleData; // x = time, y = lifeSpan, z = size, w = endSize -

167 attribute highp vec4 qt_ParticleVec; // x,y = constant velocity, z,w = acceleration -

168 attribute highp float qt_ParticleR; -

169 uniform highp mat4 qt_Matrix; -

170 uniform highp float qt_Timestamp; -

171 varying highp vec2 qt_TexCoord0; -

172 void defaultMain() { -

173 qt_TexCoord0 = qt_ParticleTex; -

174 highp float size = qt_ParticleData.z; -

175 highp float endSize = qt_ParticleData.w; -

176 highp float t = (qt_Timestamp - qt_ParticleData.x) / qt_ParticleData.y; -

177 highp float currentSize = mix(size, endSize, t * t); -

178 if (t < 0. || t > 1.) -

179 currentSize = 0.; -

180 highp vec2 pos = qt_ParticlePos -

181 - currentSize / 2. + currentSize * qt_ParticleTex // adjust size -

182 + qt_ParticleVec.xy * t * qt_ParticleData.y // apply velocity vector.. -

183 + 0.5 * qt_ParticleVec.zw * pow(t * qt_ParticleData.y, 2.); -

184 gl_Position = qt_Matrix * vec4(pos.x, pos.y, 0, 1); -

185 } -

186 \endcode -

187 -

188 defaultMain() is the same code as in the default shader, you can call this for basic -

189 particle functions and then add additional variables for custom effects. Note that -

190 the vertex shader for particles is responsible for simulating the movement of particles -

191 over time, the particle data itself only has the starting position and spawn time. -
