When I talk about the habit is from the principle and theoretical roots of the clear, we do not think??? /div>
I always for the recognition, learning knowledge to the root of the Earth, two or two life three or three born everything, know its roots can same
Knowledge is like Tai Chi, the beginning is the end, is the beginning, to do any time the potential capacity, can come and go freely, comparable to Sunding, more than the edge of the tour
The knife is fast and accurate, must be proficient in the skeleton of the path, the knife fluent, have to know the way of tendon bearing
One of the bones of the bovine bone, the flesh of the tendon, is the logical structure of our learning knowledge derived from the way
In order to expand the line, to line surface, to the surface structure, in order to form the body of the unification.
Boolean (Boolean operation) the operation of the set, the difference set, the intersection of more than two objects
The orthogonal of the set is poor, this middle school mathematics time already learned
In middle school mathematics, when it comes to this knowledge, it is in the form of a set of numbers, and now it is nothing more than a set of shapes.
Now let's talk about how Boolean operations are used in 3D graphics.
The orthogonal difference between a box and a cylinder, by which irregular graphs can be generated from the underlying graphic elements.
Now back to PS, why Boolean operations are particularly important in UI work
Is the first type aftereffect in the article I wrote yesterday.
The type is the Vector tool draws the Bai Mo, the effect is uses the layer style superposition effect to simulate the visual effect
1. Boolean operation mode and principle
2. Operational performance in 3D objects
3. The orthogonal difference relationship between the number set orthogonal difference relationship and the graph evolution from several sets of mathematics in middle school
4. Back to PS, back to the UI drawing work, said Boolean operation is a vector tool component
Now the position of Boolean operations in PS in the UI is clear.
This is part of the vector tool in PS
This is the command Operation section of the Boolean operation
Look inside the operating elements, with the previous theory and evolution of the principle is interlinked, we also know how these operations and significance
The Boolean operation is based on the same layer, which refers to a very important knowledge point.
Some people in the group sometimes ask me how I can't use Boolean operations, but it's not on the same layer.
Never think of Boolean operations as a layer operation
Because PS is a planar synthesis software
Which means all the graphics are flat on one surface.
It's not like 3DSMAX has a sense of space to tell you.
It's the problem that makes many people unable to understand Boolean operations.
I saw a 7788-square mouth Ooxx sleeping together, and he knew what the plane was doing.
Look at this picture, all of the shapes are drawn on a layer, but when we draw each shape, it goes up to the virtual plus level.
That's the way to do it, 2 based on the 1+24 13 based on the 1+2+3 keep going up
All of the time we have Boolean operations in PS, we have a layer concept in mind, and if you're in the same plane, you're in trouble.
I just started using PS when I do not know Boolean operation has a shortcut key to say, are finished and then go to point above the command, and then the more the more the more mask circle ...
ALT is-shift is + two together by the difference set
When you want to reduce the graphic, hold down ALT and draw the second shape
The other two types of operations are equally
Application of Boolean operation case: Apple logo
The history of Apple logo evolution
Well, the above information is a small series of Photoshop to the users of this software to bring a detailed perspective to understand the Boolean operation of Photoshop to share all the content of the analysis, now you see the users here are very clear, I hope to bring you useful help.
