Depth Of Field artifacts Hello, during the DOF testing, artifacts were revealed as shown in the picture: Shader code: #version 330 #algdef in vec2 texCoord; layout (location = 1) out vec3 dofFragColor; uniform sampler2D scene; // dof uniform sampler2D dofBuffer; float dof_kernel[DOF_KERNEL_SIZE]; const int DOF_LCR_SIZE = DOF_KERNEL_SIZE * 2 - 1; // left-center-right (lllcrrr) const int DOF_MEAN = DOF_LCR_SIZE / 2; void makeDofKernel(float sigma) { float sum = 0; // For accumulating the kernel values for (int x = DOF_MEAN; x < DOF_LCR_SIZE; x++) { dof_kernel[x - DOF_MEAN] = exp(-0.5 * pow((x - DOF_MEAN) / sigma, 2.0)); // Accumulate the kernel values sum += dof_kernel[x - DOF_MEAN]; } sum += sum - dof_kernel[0]; // Normalize the kernel for (int x = 0; x < DOF_KERNEL_SIZE; x++) dof_kernel[x] /= sum; } void main() { makeDofKernel(texture(dofBuffer, texCoord).r); dofFragColor = texture(scene, texCoord).rgb * dof_kernel[0]; #ifdef HORIZONTAL for(int i = 1; i < DOF_KERNEL_SIZE; i++) { dofFragColor += dof_kernel[i] * ( texture(scene, texCoord + vec2(texOffset.x * i, 0.0)).rgb + texture(scene, texCoord - vec2(texOffset.x * i, 0.0)).rgb ); } #else for(int i = 1; i < DOF_KERNEL_SIZE; i++) { dofFragColor += dof_kernel[i] * ( texture(scene, texCoord + vec2(0.0, texOffset.y * i)).rgb + texture(scene, texCoord - vec2(0.0, texOffset.y * i)).rgb ); } #endif } How can I fix this problem? I would be grateful for help. https://ift.tt/eA8V8J
