I m a 3D rookie, please 3D master come in and teach 30

I'll tell you how to make a hollowed-out board first. Generally, two-dimensional Boolean operations are used, and if three-dimensional Booleans are used, many triangles are prone to appear in Lightscape.

2. Select the circle, draw a circle in the rectangular wireframe, press the shift key, then copy a row, and select Instan, click OK

3. Select the original rectangle, right-click, select Convert To, click Convert to Editable Spline.

4. In the modification panel, if it is a single selection of attach, here it is multiple objects, so you need to select attach mult (multiple objects combined), then a dialog box will appear, select all, click attach, right-click in the blank space of the view, and all will be combined.

5. In the modification panel, click spline (wireframe), select the original rectangular wireframe in the view, find boolean (boolean) in the modification panel, select the subtraction operation in the middle, click boolean, and then select the circular line in the view, go to the top of the modification panel, click modifier list, press the e key on the keyboard, select extrude, and at the bottom - The amount below parameters selects the thickness you want to extrude.

6 ，over !!

Note: To do it in one view, left (left view), front (front view) can be, depending on your needs.

As for the spiral staircase, I forgot about it, and I'll tell you about it when it's going to be done.

3D is an abbreviation for three-dimensional, which is three-dimensional graphics. To display 3D graphics in a computer means to display a three-dimensional figure in a flat surface. Unlike the real world, where there is a real three-dimensional space, there is a real distance space.

The computer just looks like the real world, so the 3D graphics displayed on the computer just look like the real thing. One of the characteristics of the human eye is that it is near and far small, and it will form a three-dimensional effect. The reason why we can enjoy a three-dimensional image that is really like a real thing is because the difference in color gray scale when displayed on the computer screen makes the human eye have a visual illusion, and the two-dimensional computer screen is perceived as a three-dimensional image.

Based on the knowledge of color science, the protruding part of the edge of a three-dimensional object generally shows high brightness, while the concave part is dark due to the obscuration of light. This understanding is widely used to draw buttons and 3D lines on the web and in other applications. For example, if you want to draw 3D text, you will display a high-brightness color in the original position, and outline it in a low-brightness color at the bottom left or upper right position, so that the effect of 3D text will be visually created.

In the specific implementation, two 2D text of different colors can be drawn in different positions with the exact same font, and as long as the coordinates of the two characters are appropriate, it is completely possible to produce 3D text with different effects visually.

What is 3D technology?

To put it simply, it is virtual 3D technology. It is a technology that uses computer computing to achieve three-dimensional effects in visual, auditory and other aspects. From the point of view of iconography, three-dimensional is no longer flat, but three-dimensional.

The so-called "pseudo-3D" is done with multi-faceted textures. The 3D image is created directly by using 3D technology, and it is not a physical object.

The range of applications for 3D technology is extremely wide. Whether it is from military, education, production, entertainment, scientific research, or medicine, aviation, academia and many other fields will involve 3D technology.

Noun: [lottery noun] remainder.

Explanation: The remainder of a number's numeric value divided by a specified number.

Function: By counting the number of the same remainder, it can be used as one of the conditions for number selection.

Example: Such as: 33 choose 6 two-color ball 2005147 lottery number:

06,07,15,27,28,30+10, of which there are 4 (06,15,27,30) except 3 and 0, 2 (07,28) except 3 and 1, and there is no 2 except 3, then the remainder sequence is 4:2:0

Noun: [lottery noun]012 road analysis.

Explanation: 012 channel analysis is to divide each bit by 3 to get the remainder, which is 0 channels, 1 way, and 2 ways.

Noun: [lottery noun] frequency.

Aliases: Occurrences.

Explanation: Number frequency: The number of times a number appears.

Function: Used to determine the pattern of the occurrence of each number.

Example: For example, the frequency of the two-color ball red ball number 03 in the last 10 draws is 3, which means that in the last 10 draws, the number 03 has been drawn 3 times.

Noun: [lottery noun] missing.

Alias: Number of misses.

Explanation: Missing value: This is the number of periods in which a certain number does not appear. A sequence is a list of missing values for these numbers.

Missing Frequency: The total number of times a number does not appear in a row.

Missing Sequence: Refers to the sequence of missing values for each number of a set of drawn numbers. Missing sequences are used to observe the difference between missing values for a set of numbers. ** If the missing values between the numbers are not too close.

Function: 1. The frequency (number) of omission reflects the "coldness" of the number over a period of time; Usually more than 30 issues of cold numbers, you can still chase them.

2. The missing sequence is used to understand the occurrence of the number, and grasp the possibility of the future number of numbers through the judgment of a variety of intervals.

Example: 1. For example, the number 31 in the two-color ball is missing 22 times, which means that the number 31 has not appeared for 22 consecutive periods. 31 is missing 0 times, which means that the number 31 has just been opened in the last period.

2. For example, the 2005142 issue number 07 appears again in the 2005145 period, and there are two periods in the middle that have not come out, so the missing sequence of the number 07 is 2

1. Hold the "Shanghai 2011 International Logistics Equipment and Technology Exchange Conference", and make a brief description of what the venue layout contains.

aAnalyze the factors that affect the layout of the venue. For example, determine the number of participants and the size of the venue, the arrangement of the seating layout of the venue, and the atmosphere and effect of the venue.

b. Determine and divide the seating pattern of the venue. The seating pattern of the venue can be roughly divided into five types: upper and lower relative type, full enclosed type, semi-enclosed type, decentralized type, and parallel type.

c. Seating area division and seating arrangement. Appropriate and appropriate divisions are made according to different arrangement rules.

d. Arrange the basic facilities of the venue. Such as tables, chairs, podiums, fabrics, seat cards, lighting equipment, carpets, air conditioning and ventilation equipment and other infrastructure.

eSeat signs. Specifically, there are seat number signs, group signs, seat cards, table numbers, signs, seat maps, etc.

f. Arrangement of the rostrum. The following aspects should be considered, such as the seating layout of the rostrum, the podium, the recruiting stand, the microphone, the rest room, etc.

Arrangement of the G check-in counter. The principle of layout should be oriented and welcoming.

1. Come up with your plan, analyze your market prospects, and find venture capital.

2. Register a leather bag company and use the state to subsidize the development of new energy.
