Oblique heap, oblique heap scoi
The difference between the diagonal heap and the left heap is that the Left heap only exchanges the positions of the two children when the npl of the right child is greater than the npl of the left child, the oblique heap is exchanged in any way:

"Diablo 3" will be set in a 45-degree oblique angle. This seemingly insignificant piece of news a few months ago has kept me in memory, constantly trying to understand why the dark team of the master to abandon the current mainstream of the 3D route and return to 2d,b big word miju: To achieve the flow like a flowing RPG combat experience , only use oblique angle of view 2D manifestation, as for one of the
position is much easier.As follows:The top of the picture preface, anyway above this picture I understand. So our coordinates start and end point value actually becomes, the length of the black bracket and the length value of the purple bracket is how many!Although many people do not like math, but the geometry should be good, we come together to calculate ...ZXX: Length calculation ...The result is, the starting point:MATH.SQRT (2) = 141.4213562373095;The end point is:* MATH.SQRT (2) = 282.842
Excel makes the table, the indispensable operation is--make oblique table head, the following method may look, hope to bring you help
First Law:
1, select the cell, point format, cell, border, first select the thin solid style, and then point Slash, and then select a slightly thicker solid line, and then point outside the border of the icon, so that the border is painted;
2, then select the cell, point format, alignment, horizontal alignment to sel
The implementation of the priority queue structure is mainly completed through the heap, mainly including: Binary heap, d heap, left heap, oblique heap, two heap, Fibonacci heap, pairing heap and so on.
1. Binary heap 1.1. Definition
Complete Binary Tree, minimum root.
Sequence is used for storage.
1.2. Operation (1). insert (filtering)
Insert 26 at the end and compare them upwards. If the value is greater than 26, the switch position is displayed. I
The use of transform. matrix is cumbersome, but its advantage is its powerful functionality: The Matrix. Concat () method can be used to easily oblique deformation of display objects:
VaR mymatrix: matrix = matrix_rect.transform.matrix;
VaR tempx, Tempy;
Tempx = matrix_rect.x + matrix_rect.width/2;
Tempy = matrix_rect.y + matrix_rect.height/2;
Mymatrix. Translate (-tempx,-Tempy );

DescriptionThe inclined heap (skew heap) is a common data structure. It is also a binary tree and satisfies the same heap properties as a two-fork heap: The value of each non-root nodeIs bigger than his father. Therefore, the value of the root is the smallest in the whole inclined heap. But the oblique heap
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.

Some time ago, the implementation of dynamic surface inversion and refraction was done. In this case, the camera needs to be set up at different locations on the surface of the water, and the scene texture under the refraction or reflection needs to be generated for the cropping plane on the water surface. You can use the cropping plane method provided by d3d or the custom shader method. Another method is to directly modify the projection matrix to change the original near plane to a specified p
The map occupies an important part of the RPG game. It is the platform for the game to unfold. So I am very simple to use the interface of the map, it must be too complex to bring the inconvenience of use.
Map interface: Sets the map size, sets the size of the map block, maps the scene to the specified ID, and generates a map based on the size of the specified picture and map block.
RPG maps are generally multi-layered: background layers, occlusion objects, and events. The background layer is ma
This article mainly introduces how to implement JS to make webpage background images move diagonally. It involves javascript techniques for operating background image effects and has some reference value, if you need it, refer to the example in this article to describe how JS achieves oblique movement of webpage background images. Share it with you for your reference. The specific implementation method is as follows:
The Code is as follows:

It is essentially the projection of each point of a graph in three-dimensional space onto a two-dimensional plane (in fact, the y-coordinate must be divided by 2, but this is not the point). After projecting the coordinates down to two dimensions, it is possible to draw each point on a two-dimensional paper, thus drawing out the entire graph.(Oblique two-measurement, 200px side length of the cube)When learning vectors, some transformation formulas wer
Sometimes the priority queue needs to be merged. For a binary heap, the heap can only be created with the complexity of O (n) because it has nothing except the key value and the heap sequence.
To reduce the complexity of merging to O (logn), you can use oblique heap (left-side tree), two-item heap, and other data structures. The Fibonacci heap is even better. Many operations are the theoretical complexity of O (1), but the complexity of thinking and
The approach of the oblique table head:
Method One:
Practices
1, select the cell, dot format, cell, border, first select the thin solid line (see figure II), and then point slash (see figure III), and then select a slightly thicker solid line (see figure IV), and then click on the outer border of the icon (see figure V), so the border is painted;
2, then select the cell, point format, alignment, horizontal alignment to select the norma
this is too irregular. A angle where the tangent is 0.5 does has a nice regular pattern:two steps to the right and one step up. Thus, the isometric projection used by most games tilt the X-and z-axes with approximately degrees (the exact angle is "Arctangent (0.5)"). By the, because the tangent of the angle of the rhombus are 0.5, the rhombus is twice as wide as it's high. Many sources mention a 1:2 scale for isometric perspectives. (To make the edges of the rhombuses match, the width of the rh
