Download tinyline 2D Tinyline 2D is a j2-class library for high-performance 2D graphics. tinyline 2D is j2_sdk intended to expand the 2D graphics capabilities of j2_on mobile devices. the SDK supports the SVG Tiny imaging model. it is a bedrock of the tinyline SVG toolkit.

I'm using unity and spritemanager 2 to make a 2D game for the iPhone/iPad. using the shader has ded with SM2 and/or the mobile vertex colored shaders has ded with unity left me extremely GPU/fillrate bound on the iPad in particle. I was seeing anywhere from 50-90 ms per frame for "CPU-waits-GPU" from the internal profiler running on the iPad. I wrote my own shaders and dropped this to an average of 10 ms per frame. I 've still got a few Optimizations

1 Preface When using quartz 2D drawing, we usually use the subclass of uiview. Think about the drawrect of this class: add the quartz function call to the method. This method is called every time you need to repaint the view.2. Details In quartz 2D, like other core graphics, plotting is performed in the graphic context. Generally, it is called only the context. When drawing, We need to retrieve the current

Let's take a look at the official website introduction: Vortex2d. net is free 2D fast graphics framework/game engine powered by direct3d 9. it is replacement of xNa for 2D games development. vortex2d API is very well structured, easy for beginners and powerful for professionals. programming Language: C #; OS:

Scene transform |2d and 3D mutual conversion in OpenGLwe live in a three-dimensional world-if we want to observe an object, we can:1, from a different position to observe it. (View transform)2, move or rotate it, of course, if it is only the object inside the computer, we can also enlarge or reduce it. (Model Transformation)3, if the object is drawn down, we can choose: whether a "near-large far small" perspective effect is required. In addition, we m

GitHub Address: https://github.com/wsgzxl/ Qlgame2dengine say five questions today: 1. The question of the wrong color in the front, It is because the data format Freeimage read out is inconsistent with the order of OpenGL display, so some colors are wrong and have been processed in the Texturemanager class Texturemanager::fibitmap2glbitmap Method! 2. png transparent images are rendered using the glenable (Gl_blend); Glblendfunc (Gl_src_alpha,gl_one_minus_src_alpha); Note that these tw

Write in frontWrite an article a year ago. Before looking over 2015 years of Siggraph Course (on the rendering can go to Selfshadow's blog found, very full) when you see the volume cloud rendering. This course tells the developer of the dynamic weather system developed for the game "Horizon: Dawn", which focuses on the simulation and rendering of the cloud inside, and it is valuable for reference. Among them, the cloud modelling mainly uses the Raymarching method, their inspiration should

Introduction of conversionConversion overview-conversion is an effect that changes the shape, size, and position of an element-also known as Warp, that is, you can apply 2D or 3D transformations to elements to rotate, scale, move, or skew elements-2D Conversion: Changes the elements on the x-axis and y-axis planes, changing their shape, size, and position650) this.width=650; "src=" Http://s1.51cto.com/wyfs0

Transform performs 2d and 3d deformation (css Animation 1), transformcssThis is my understanding and arrangement after learning. If you have any errors or questions, please correct them and I will keep updating them! For some time, I did not clarify the relationships between transform, translate, transition, and animation. Now I want to sort it out: Translate: translation. It is an attribute of transform; Transform: deformation. It is a static att

AMD's recently released catalyst 10.6 driver package not only brings a lot of new features and game performance improvements to Windows systems, but also changes significantly in Linux systems, for example, the new 2D acceleration architecture is used by default, Red Hat Enterprise Linux 5.5 is officially supported, and OpenGL 4.0/3.3 is officially supported. In particular, the 2D acceleration architecture

Guidance: 　　 Introduction 　　 Definition of a point A point can be represented in 2D space as a pair of numbers, one for each of the X and Y axis: 　　 Distance between two points The distance between two points 　　 DX = Ax-bx DY = Ay- Distance = SQRT (dx * dx + dy * Dy) 　　 Definition of a vector A vector can be thought of in two ways: either a point at or a line going from the origin Vectors are often used to describe direction.
