15.010 what is the difference between transparent, translucent, And blended primitives? A transparent physical material shows objects behind it as unobscured and doesn' t reflect light off its surface. clear glass is a nearly transparent material. although glass allows most light to pass through unobscured, in reality it also reflects some light. A perfectly transparent material is completely invisible. A translucent physical material shows objects behind it, but those objects are

If you want to use Photoshop often, then you need to understand a simple but not easy to understand feature of Photoshop--blending mode. This is a very easy to ignore feature in many of Photoshop's cool features, but after reading this article, hopefully it will attract your attention. 　　Where is the blending mode? The biggest reason why a blending

prior to the use of mixed in the project, but the research is not in-depth, the recent art of a need to make me determined to re-delve into the mix and its cocos2d-x in the use of, here to share to everyone. Blending ( Blend , some translation books call it blending, hereinafter referred to as blending, OpenGL , when an INPUT element passes through all relevant

write in frontThe question of Alpha has always been a more confusing thing, especially when it comes to translucency, and I don't know why A is blocking B, and B is in front of a. This article summarizes what I now know ~The alpha test and alpha blending are two methods of processing transparency.Alpha Test uses a very overbearing and extreme mechanism, as long as a pixel of alpha does not meet the conditions, then it will be fragment shader discard,

Shaderlab syntax:blending MixBlending is used to make transparent objects.Mixing is used to make transparent objects.When graphics is rendered, after all shaders has executed and all textures has been applied, the pixels is written to The screen. How they was combined with the already there was controlled by the Blend command.After all the shaders have been executed, all the textures are applied and all the pixels are ready to be rendered to the screen, using the blend command to manipulate the

farther of B to a closer a, but the order of alpha blending is non-exchangeable) or the entire B is discarded directly. This is not good!Conclusion: The depth buffer is perfect for opaque objects, but it is useless for transparent objects.2 painter algorithmSince the depth buffer algorithm cannot correctly draw transparent objects in the wrong order, there must be a simple fix, right? As long as we are always guaranteed to draw in the right order! We

Su-Color on the previous article mentions the application of "computing", the core for the channel application "layer blending" mode to get the selection, and, Suseshun brings up the "layer blending" appeared in three places: One is the mixture between the top and bottom layers, appearing in the Layer menu bar; The second is "Application Image" toolbar, channel or channel to the layer of the use of "layer

Color Blending In environment mapping and fog effects, when the final color is generated, the color is blend (mixed) operation. And this blending is performed in the same pixel shader, so there are no two separate colors in render target, and a blend color. But color blending is a different form of mixing that is applied when a specified pixel in a frame buffer

Many of the sonar readers of flying fish often ask me how the light effect of the button like in is done? In fact, it's very simple to create a new layer, brush or ellipse to draw white, Gaussian blur, and then change the layer blending mode to layer overlay. However, in this article we do not discuss the specific technology, and to see as the above button through the white overlay to create a button of the highlight, we have to understand a layer of

Suppose we have a lot of machine learning algorithms (which can be any one we've learned before), can we use them at the same time to improve the performance of our algorithms? Also namely: Three Stooges equals.There are several ways to aggregation:Some of the poor performance of machine learning algorithm (weak algorithm), how to aggregation, become a better performance algorithm? Take a look:We can see that sometimes aggregation performance is like doing feature transform, and sometimes it's l
