The light from this parallel light source,Based on the normal vector of vertex and the direction of light (light vector,To a certain exten

Time and motion In ancient times, there was a timer with n numbers starting from 1 ~ Then there are three tracks corresponding to 1 minute, 5 minutes, and 1 hour. For example, each track has a ball for 1 hour and 6 minutes. The timer works by rolling out a ball from the ball heap every minute to a one-minute track (the ball heap is a queue). In special cases, there are four balls on the one-minute track, if you ente

From 1 billion light years to 0.1 flying meters (Classic! Shocking !)

Where is the Earth? 10 million km. Oh! Big trap, small circle ~ It is the orbit in which the moon travels around the earth! 1 million km. What is this? 0.1 million km. It's the earth !!! Home!

The key enables the solid to have strength and corresponding electrical and thermal properties. For example, strong keys result in high melting points, high modulus of elasticity, short atomic spacing, and low coeffic

Basic knowledge of Optical drive

I. Basic knowledge of optical drive Before you choose a good CD-ROM drive, understand some of the concepts about the optical drive. First I say what is CLV and CA V disc and hard disk work in a very different way, the disc of the hard disk is divided into concentric circles, these concentric circles become the track, each track is divided into a number of sectors, the file is stored in these sectors, therefore, the disk of the hard drive is always rotating at a constant angular speed, which is

Vegas 7, copy the Golden Dome material, put in the bottom of the original rail to do the reflection, it flattened and vertical reversal, adjust the position and forward to the bottom of the material, the transparency adjustment of 60%. 8, copy the second layer of track to the new rail, the new rail adjustment to the reflection of the orbit, as a mapping track. Change the layer blending mode of the reflection track to "Custom"/"Height

lines in the light represent the orbits of the lights, and the direction changes when the faces collide with the face of the light. In this way, the direction of the surface that forms the model can be left and right in orbit. The light in 3D, just to a certain extent in the simulation of light, There is no need to fully simulate the real world of light in orbit and motion. because of the full simulatio

An animated tutorial for interpreting the late synthesis of long exposure photography

For those who like to take pictures of the scenery, we may have tried for a long time exposure, longer exposure time will often bring out another feature of the scene, because of this, it has also become a favorite part of the film friends shooting means. The pleasure of my first long exposure was to record the flow of traffic with a slow door, and then to record the state of the water, the vastness and magnificence of the sky, the recording of the star orb
