camera drawing

good practice to put the user interface on a different layer and then render the UI layer separately with a separate camera.In order for the UI to appear at the top of other camera views, you also need to set the purge mark to depth only, and make sure that the UI camera's depth is higher than the other camera.2. Here are a few steps to demonstrate the two properties of the camera:First create two cameras

Add the Gicanvasview view in storyboard and create the associated variable Canvas_ in Viewcontroller:@interface Viewcontroller () { __weak iboutlet gicanvasview *canvas_;} @end To add a button picture resource, set the command toolbar:-(void) viewdidload { [super viewdidload]; Canvas_.tools = @[@{@ "image": @ "Select.png", @ "name": @ "select"}, @{@ "image": @ "brush.png" @ "name": @ "splines"}, @{@ "image": @ "Line.png", @ "name": @ "line"},

Here is the main point is to draw pictures, so-called drawing pictures, is the external picture information loaded into memory and then by the Java compiler to draw, generally feel compared to B/s development some trouble, not to say the principle of trouble, their principles are actually the same, not the same is the complexity of their implementation process, to rewrite the method , loading pictures, displaying pictures, etc. However, there is a cer

Interesting questions: Drawing (c ++ implementation) and interesting drawing Description: on a paper that defines the Cartesian coordinate system, draw a rectangle (x1, y1) to (x2, y2) That ranges the abscissa from x1 to x2, colors the area from y1 to y2. An example of drawing two rectangles is given. The first rectangle is (1, 1) to (4, 4), expressed in green an

my friend asked me how to pull the map and how to pick my hair, because he wanted to change the white background of the registration photos to the blue one, lest he should go to the photo again. So he told him about a dozen ways to pull the map and alternative approach, think or summarize, and share with you. Because I also found that a lot of people are obsessed with drawing. And in doing picture synthesis, there will be countless times are trying

PHP drawing to generate pie chart method, PHP drawing generated pie In this paper, we describe the method of generating pie chart of PHP drawing. Share to everyone for your reference. Specific as follows: The function to be implemented here is the population distribution ratio chart, which consists of a circle of sectors, each of which is not the same color.Copy

OverviewThis article implements the following program: ( draw a variety of different styles of lines in the form )The main steps are as follows:1. Create a new project in Eric6, create a new form2, (automatically open) into PyQt5 Desinger, edit the GUI, save3, back to Eric 6, to the previous step to get the interface file Drawing.ui file right-click, compile the form, get ui_drawing.py file4, then right-click on the Drawing.ui file, generate dialog code, get drawing.py file.

Friendly tips, if you cancel the lock screen under the state of the photo machine then you will find that we can not directly achieve a quick photo shoot oh. 1. In standby mode, click "Application". 2. Click "Set". 3. Click on "Lock Screen". 4. The "Camera shortcuts" to the hook to cancel. Set the effect chart contrast: Well, after that, if you want to take a picture, you only have to unlock it before y

control to implement a real-time camera preview screen.Surfaceview is a subclass of view, so it has all the methods and properties of view. At the same time, the extra surface is dedicated to drawing classes.Surfaceview has the following three features: A. 具有独立的绘图表面； B. 需要在宿主窗口上挖一个洞来显示自己； C. 它的UI绘制可以在独立的线程中进行，这样就可以进行复杂的UI绘制，并且不会影响应用程序的主线程响应用户输入。The implementation principle analysis of Surfaceview
