  • QT + OpenGL 14 multi light source mixing problem


    We have studied the different light sources in each, but we have implemented them separately. There are often multiple light sources in a scene. So we have to consider this situation. In order to see the effect, we need to first come to a terrain, download the terrain model and draw it directly according to […]

  • Thingjs provides the basic method of light configuration to save development energy!


    3D software can create the freedom of any type of light at will, but the realistic effect still takes a lot of effort. Thingjs provides the basic method of light configuration to save development energy!Lighting helps to express an emotion or guide the audience’s eyes to a specific position. Light can reflect a tone, which […]

  • ISP Foundation (06): AWB algorithm


    1. AWB overview People’s vision and nervous system have color constancy. When they see white objects, they are not affected by the environment. For example, in cloudy, sunny, indoor, outdoor, fluorescent lamp, incandescent lamp and other environments, the color of white paper in human vision basically remains unchanged, but image sensor, an electronic device, has […]

  • Lighting rendering — simulating lighting effect with canvas


    illumination We can see objects because light shines on them and then reflects back into our eyes. There are many influencing factors: the position of the observer, the position of the light source, the color of the light, the color of the surface of the object, the material and the roughness, etc. In the future, […]
