The world is changing really fast, the previous period of time Windows development technology hot still in full swing, web technology began menacing, just as the web presents a thriving, Android small robot, bite the apple, Winphone development platform and lightning-like cut the chaotic web world.I believe many developers are wondering why the world is not around me. But I'm around the world turning. My answer is that the Shaolin monks learn to fight, the first to learn to stand pile. To practi
The details are added slowly, there are a few things to be aware of, must have received the projection of the pass is name is Shadowcollector, must add #pragma multi_compile_fwdbase, the object's shader must have the tag inside the {" Lightmode "=" Forwardbase "}. The processing projection should be in the shader of the object receiving the projection.Then there are three macros.Shadow_coords The argument b
Cylindrical projection is to project a two-dimensional image to a three-dimensional cylinder, but it is still presented in two-dimensional form when displaying the image.
The most important step of projection is to calculate the projection transformation formula, which is similar to image rotation. As long as the transformation formula is obtained, it is easy to
The reverse projection of an image replaces the pixel value with the bin value of the histogram at a certain position of the input image (multidimensional or grayscale, therefore, the obtained reverse projection chart is single-pass. In statistical terms, the value of the output pixel point is the probability of the observed Array under a certain distribution (histogram.

Recently, by studying the raster process of the Fixed rendering pipeline, I finally understood the cause of the distortion.
Let's first set V = the vertex before the projection transformation, V '= the Qi vertex after the projection transformation.
In the screen space, the properties of V are not linear, but 1/VZ is linear, other vertex at
Since the normalized coordinate system used by the device is not pixel-independent, the range is -1~1 in three directions, so the direct hard-coded drawing of the entity may result in horizontal or vertical compression (distortion) of the device pixel problem.The solution in the book is to put the operation in a virtual coordinate space, that is, we design the vertex value when the illusion is in the virtual coordinate space, as to how to map to the device, you can not consider.Orthographic
In today's most popular flat design, long projections are looked at with proven design skills. Today teach you a method of making long projection, how to use PS and CSS3 respectively how to achieve long projection effect.
For example, the following is a very classic long projection design:
Photographers often choose long projections to bring dramatic effects
The WebKit engine defines the-webkit-box-reflect property, which enables the projection effect, with the following syntax:-webkit-box-reflect: The property values are described as follows:When the object source changes, the projection is automatically updated, and when the mouse passes over the object, you can see the mouse effect in the projection, and if the pr
We are in many mobile phone app icon will see the oblique projection effect of the graph, this oblique projection effect has been popular for some time, then oblique projection effect is how to do it? The following small series to teach you.

2) We do not set the FOV of the YZ plane to be the same as the FOV of the XZ plane, but instead make the aspect ratio of the view plane the same as the width to height ratio of the screen. In this way, the upper and lower cutting surface of the equation will be changed, directly will appear in the superfluous on both sides of the thing cut off, that is, after the 3D space cutting done, and then projecte
Today, the editor teaches you how to use Photoshop to add a realistic projection for a physical image, and the effect is very beautiful. you can join your favorite friends to learn how to use Photoshop to add a realistic projection for the physical image, the effect is very good. it is very simple and practical for friends who like to learn how to add projection
The process of producing a target scene is similar to taking a picture with a camera:(1) Secure the camera to the tripod and let him view the scene from a different location in the scene ( views transform ) Glulookat(2) Arranging the scene so that the position of each object in the photo is what we want to move, rotate or enlarge the object in the scene ( model transformation ) gltranslate*, glrotate*, glscale*(3) Select the camera lens and adjust the magnification (focus) Display object, you ca
maximum contour and projection The most recent use of the maximum contour and projection operations. In retrospect, these two algorithms are indeed very common basic algorithms. summarized here and extracted. Maximum profile: The premise is that the image is processed by grayscale and threshold, and the results of canny can be processed directly, and in some cases it needs to be converted in color domain

Through seamless fusion technology, using multiple projection (channel) composed of circular projection scr

How can I change the downloaded image to the country's 2000 coordinates?
Note:To convert a projection to a cgcs2000 coordinate system, you need to download a non-offset satellite image for conversion. an offset conversion will cause the converted satellite image to be distorted, the coordinates are incorrect, and registration fails.
Step 1: select a map source without offset to download the satellite image you need.
Step 2: select the toolbar on the r
Webmaster currently launched the cheapest interactive projection system, so that more people can access this new form of interaction, please go to my website http://www.vvvision.net to view.
Interactive projection has been very popular recently, but it is very expensive. Recently I have studied it. The principle is actually very simple.
We know that light is an electromagnetic wave, and its wavelength range
MONGDB Basic Learning (v)--projection, pagination, sorting, aggregationThe learning of Basic grammarThe new Year is coming soon, tomorrow is a lover, the day after tomorrow will be a holiday, hope that they can in the holiday before the five and six chapters finish. I'm glad to see that yesterday I wrote "MongoDB for Java" Java Operation MongoDB "can be placed on the front page of the CSDN blog, the content of this chapter is as follows:

Projection operation, at first glance do not know what to say. So what is a projection operation? In fact, is the select operation, the name of the strange. Is the same as the select operation in a LINQ query expression. It is able to select elements in the data source and specify the representation of the elements. The projection operation consists of the follow
The following example shows how to use perspective projection to create 3D space. The example shows how to projectionCenter modify the vanishing point and change the perspective projection of space through properties. After this modification, the recalculation is forced focalLength and fieldOfView (and its associated 3D space warp).This example:
