Most barcode generation algorithms will give you a compact barcode usually with the smallest element size being one pixel. Barcode readers generally work faster and more accurately when the edges are crisp and then size of the lines or dots are precise. They are usually made of black dots or lines on a white background. I've come across this problem many times over the years and still live in hope that there is an easy way to do this that I have missed. Std::cout << "lightCount value = " << *(int*)ptr << "\n" Void* ptr = glMapBuffer(GL_SHADER_STORAGE_BUFFER, GL_READ_ONLY) GlBufferSubData(GL_SHADER_STORAGE_BUFFER, sizeof(int), sizeof(LightData) * lights.size(), &lights) GlBufferSubData(GL_SHADER_STORAGE_BUFFER, 0, sizeof(int), &lightCount) GlBufferData(GL_SHADER_STORAGE_BUFFER, sizeof(int) + sizeof(LightData) * 10, NULL, GL_DYNAMIC_DRAW) GlBindBufferBase(GL_SHADER_STORAGE_BUFFER, 0, lightSSBO) Target machine: Raspberry Pi 3B (1GB RAM, Broadcom something-or-other) 4 cores 1.4GHz + Ubuntu Server for Pi I apologise, but I would seriously appreciate any pointers.Įxtra notes: I'm writing for/on Linux embedded devices over the DRI/M interface.Īs per Richard's comment, some information about my systemĭevelopment machine: Dell inspiron 15 7570, 16GB RAM, i7 8core + Ubuntu 21.04
