Optimize Triangle Mesh Vertex
For personal use only, do not reprint, do not use for any commercial purposes.For the same triangle mesh, It is faster to use TriangleList or TriangleStrip for rendering. Where is the speed? Most people think that strip is faster, because strip has a better cache. Such an answer is actually totally wrong. For mesh arranged in the s
Deep understanding and application of Float attributes, deep understanding of float attributesI. Features of Float
1. Applied to text-centered Images
2. Create a block-level box
3. Multi-column floating Layout
4. The width and height of the floating element are adaptive, but the value can be set.Ii. Core Issues
Text surrounding image: img labels and multiple text

The float (float) of the CSS moves the element left or right, and the elements around it are rearranged.Float (float) is often used for images, but it is as useful in layout.The horizontal direction of the element floats, meaning that the element can only move left and right without moving up or down. A floating element moves as far as possible to the left or rig

In the previous article, we introduced how to convert vertices and texture data of ply files into mesh files, but there is no texture data yet. This article describes how to add textures. The Code is as follows:

The trinocular operator is an important part of C language. The conditional operator is the only operator with three operands, also known as a ternary operator.In C-style languages, the ternary operator is in the following form:But there is no such operator in Python, and before Python 2.5, you can represent the ternary operator in the following waywhere c is the condition, if C is not true, then the first element x in the progenitor is returned, and if C is set, then the second element y is ret
In the process of writing a page layout, floating is a common attribute that is used by everyone. In a lot of typesetting layout is used in the floating, for example, the following places are applied to the floating.When I learn to float, but I have to boil the brain, here I share my knowledge of floating this piece of the summary.First, the definition of floatingMoves the element out of the document stream, moving in the specified direction (left or

What is spline Mesh?Unreal 4 engine and unity3d A major difference is: Unreal 4 engine provides a very very many kinds of functions. This is because epic also develops games and is a very successful masterpiece. They will integrate some of the features that have been validated in the game project and can be reused by other developers to the engine layer. So the Unreal 4 engine has a lot to learn, but if you get the most out of it, it's probably easier
A summary of your own after reading the article: the three-mesh operator is faster than if-else in the absence of compiler optimizations, because the three-mesh operator also uses an extra temporary variable, which first operations and then replicates, If-else is directly assigned, so the speed is fast, But now the compiler has to do these optimizations, the optimized assembly code is the same, just like i

Discard those useless methods, only remember the most practical one way!Add a class attribute to the parent element to clear the float: clearfix!!!The styles are as follows:. clearfix:after{Content: ".";Display:block;height:0;Clear:both;Visibility:hidden;}In order to be compatible with IE6,IE7 (now the project is almost completely out of consideration). clearfix{Zoom:1}Clear float is so simple, can be used
Comments:
In CSS, float is often used for layout, that is, float: Left or float: Right. In simple terms, the former is left floating (non-floating elements floating forward to the left side, if the elements are all float elements, they will float from left to right according
