All the assignment for 3D animation are finished!

Finally I finish the assignment for 3D animation. Before the end of the assignment, I still cannot imagine what s the feeling after finish all the assignment in 3D animation.Because the assignment is like endless work, we have redo and redo , improve and improve to achieve the satisfaction.

When doing the assignment, we have to learn more and more function to achieve our goal. But when I stop doing it for a few day, I will forgot how I did it and have to find again. 3Dmax have to much function inside, everyday have to suffer in finding function.

But today, due to the assignment, I finally understand that we have a lot of way to making a 3D object. Every modeler have their own way to model a 3D object. Also backup and saved the project anytime in case the project crash sometime.

Thank for my tutor helping me in my assignment and pass on the techniques to us. I really learn a lot of things in this subject.

Rendering Issue

For the third assignment of 3D animation, we have to render video with 30 second to see how the camera move.To render the 3D scene, out tutors prefer using mental ray and load "sky lighting.daylighting". This renderer is best for us to make the video become beautiful.

But this blog are made to inform everyone that to rendering a beautiful scene should not using laptop but desktops PCs. Because my laptop will take about 4 to 5 minute just for render one frame. If using laptop to render this 24x30 frames(1 second has 24 frames), the laptop will screwed up. To render my video, I used 3 desktop PCs with rendered it more than 12 hours.

Also, there is a lot of problem pop out when I rendering my video, the rendering is finished but the video cannot be played and it forced me to render again when I only using 1 desktop PC. Therefore, the next rendering, I using 3 desktop PCs to separate their pressure and also reduce the risk.

Making camera move

We must moving the camera view in creative way in doing assignment 3 for 3D animation. Actually, this assignment will be easier than assignment 2(making building). But it will take some hour to get familiar with this.

To moving a camera in easy way, we draw a line to make the camera follow the path of the line we draw(translate position), but the camera will only look at one direction so we just need to set key frame for the rotation of camera.  With this way, we no need to set key frame to make the camera move.

If it is too hard to control the rotation of camera, we could also set a target to the camera to look at.

If we get familiar to play with the camera, it is actually quite fun.

Making 3D building

When doing the assignment 2 of 3D animation which is modelling 4 building. The most important function for me to create building is boolean. This function allow us to combine two object or either cut a object with the other object.


Also, I will show my result of the building in this blog.


For this building only, I used boolean function for its balcony by using curve box boolean with another normal box to get the shape of the landing space. Same as well with the window and rooftop. Therefore, if everyone don't know how to a weird and complex shape, try to use boolean to get that shape. In this assignment, I also learn that we must very patient to make the 3D buildings.

3 type of 3D mapping which is commonly used in 3ds Maxs

In the lecture, I learn the 3D mapping, which is very helpful in making 3D model. What is 3D mapping? It is a technology that creates three-dimensional views of objects on computer screens. 

There is 3 way of 3D mapping which commonly used:

1.Displacement map.

->The most useful mapping methods. It help us to create the depth by the black and white color of a picture. (Black color is the concave and white color is convex.)

2.Specular map

->It help us to create refraction field to an object by using the picture.( The section with white color will refract the light.)

3.Bump map(don’t need photoshop)

->Create texture feel. This mapping could create the depth and texture quickly by just create it in 3Ds maxs.

As game designer, 3D mapping is very important because it help to reduce poly count in 3D model, lower the poly used in 3D, smoother the game play.

Why human can see black color?

In latest lecture, lecturer give us a question about why people can see black color...and no one can answer this question. We suppose to know this question since secondary school...Therefore, I going to do a revision for this.

Question:

Why people able to see black color object?

We can see the object because it reflect the light into our eyes. But black color can absorb light, it won't reflect any light, then how people see the black color object?

In my research, we able to see red color light, blue color light, green color light....White light is the combination of all light color, but we cannot see black light. It is because black color will absorb the all the light, there is no black color light.

We can see the black color object, but cannot see the black object if in the dark condition. This mean we can see the black color object not because of the reflection of light, but through the contrast of the black color object and other object color. In other words, if the other object color will reflect the red light,blue light, green light and other light to our eyes, then we able to see the black color object. 

Three point lighting

Next class, my lecturer will teach us about what is three point lighting. To ensure me to understand what lecturer talking about, I decide to do some research about the three point lighting.

As its name, three point lighting is a method to light up the subject by using 3 light source which can greatly emphasize the silhouette of an subject.

Three light source in three point lighting:

1.Key light
-Is the main light source, usually is the strongest light in between. Commonly, it place in around front of the subject. Key light light up the whole image. It shine directly upon the subject.

2.Fill light
-Using a weaker light compare with key light, but bigger area. Commonly, it place in beside the key light. Fill light could increase overall brightness and also create good refraction of light of the subject.

3.Back light/Rim
- Produce weakest light from the back of the subject. It used in separate the subject from the background and look like having a certain distance.

In my opinion, three point lighting able to make the image look more interesting and make the subject could be see clearly. This method could really help us in making 3D model because, the 3D without light is look so boring and difficult to see the shape of it.
