sphere cast

Set the circle radius r = 1.5, the cylinder height H = 3, the circumference is long, circle area, sphere surface area, sphere volume, cylinder volume//requirements: With scanf input data, take the decimal point two # # # # # "C" Set Circle radius r = 1.5, cylinder height h = 3, circle length, circle area, sphere surface area,

input data with scanf, the output of the calculation results require a text description, take the decimal point after 2 digits. the circumference length, circle area, sphere surface area, sphere volume and cylinder volume are obtained. Program:#include int main (){float H,r,c,s,sq,vq,vz;float pi = 3.141526;printf ("Please input circle radius r, Cylinder high H:");scanf ("%f,%f", r,h);c = 2 * PI*R;s = pi*r*r

Unity creates a sphere the default is not to see the inside of the sphere, so you need to use cull Front to modify the direction of culling, which will bring a new problem,The video being played is flipped like a mirror, so change its UV coordinates so that it flips over to float u_x=1-i.uv.x; float u_y=i.uv.y; i.uv=float2(u_x,u_y); 1Shader"Unlit/unlitshader"2 {3 Properties4 {5_maintex

The ball is closely related to the circle. One is three-dimensional and the other is two-dimensional. For details, see circle and elliptical.

The following articles are reproduced to http://blog.csdn.net/i_dovelemon/article/details/32904251, thanks to bloggers for sharing knowledge and learning from bloggers. Introduction In 3D collision detection, in order to speed up the efficiency of collision detection and reduce unnecessary collision detection, basic geometry is used as the bounding body of the object (bounding Volume, BV) for testing. Collision detection of the basic bounding body is relatively inexpensive and much easier,

Java api public T cast(Object obj); Casts an object to the class or interface representedThe general explanation means to replace an object with a class or interface.2.

Labels: Graphics OpenGL I haven't updated my blog for a long time. I recently studied OpenGL graphics programming and wrote some interesting programs. Let's talk about it. The sphere is widely used as a basic geometric image in game programs. The most well-known is that it can be used as a sky dome to simulate the sky, which is more detailed than the sky box, even with other special effects, it is not easy to wear. We should have learned

We can use a sphere as the sky dome to simulate the sky. Sky Dome is the sky dome. It is a way to simulate the sky in 3D scenarios. The sky simulated by Sky Dome is more realistic than sky box, it is easy to apply the fog effect to sky box scenarios, but sky dome does not. Because sky box is a square, the distance from the viewpoint to each vertex is not equal, and sky dome is a sphere, when the viewpoint i

Hello everyone, github.com/tuohai666 (the sea) today to share the Sharding-sphere launched by the blockbuster products: sharding-proxy! In the previous Sharding-sphere 3.0.0.M1, the first release of the Sharding-proxy, the new product in the end? This hope through a few optimization practice, let everybody glimpse, from a few details point can imagine sharding-proxy of the whole picture. More detailed MySQL

Recently, due to interest, I began to learn OpenGL plotting. This article uses "Draw sphere" as a point to summarize what we have learned recently. > OpenGL ES started with OpenGL from Android. As we all know, Android View is thread unsafe, so it is only allowed to operate on the View in the main thread. However, if we need to implement a complex interface, especially for game development, and draw a large number of images in the main thread, it will
