Body of the bus

First, by creating the model, the body of the object is the most important part. You need to start with the body. This can make things easier , simpler and less confusing. I start with a polygon cube. I use edge ring tool to cut the edges and I arrange the edges properly, to make it look like the shape of the bus. After that , I try smoothing it. It turn out to be a unsuccessful one. It looks like there are extra edges or vertices hidden underneath each other. This is because some part has a colour that is abit darker. I try to consult teacher for help as I tried a lot of time but the problem cannot be solved and I cannot continue with my project. The mistake is that I have cut too many edges to get the shape of the body of the bus. Actually, to get the shape, I do not need to cut too many edges. The shape is determined on where you cut the edges and how do I arrange the edges and vertices. With the help, I finally complete the body of my bus after a few days of struggling. I have learned from my mistake and I would take note of this, next time will remember and be extra careful.

Next creating the windows is simple, using polygon cube and create the shape, actual size and duplicate it. However, the difficulty is to arrange them proportionately accordingly to the distance and sizes, not all windows have the same size. The windows plays a important role of my bus model. In all, I still can manage it. Its not easy modeling from start with just image plane. Follow by, the window is transparent. I need to try assigning new materials > blinn and playing around with the transparency tab, scaling it down, but it does not work. The effect is there but it cannot be seen through. I need to see through it in order to see the seats inside the bus. Therefore, I tried looking, referring to tutorial video on youtube. Searching ways to solve my problems. Finally I found a solution to my problem. Using photoshop, make the stage transparent> save the file> then assign new materials for the windows> lambert. Under the colour tab( at tha side)(small checkerbox) click and I import the file I have save in. After this is done, I press 6 then the material or transparency is being applied to my windows. Hence, I just need to adjust the transparency tab > scale down to get the transparent effect. Now I can see the seats inside. My problem is solved.

(*If I delete the faces of the bus body where my windows are place, the effect of transparency can be seen when look through the windows. In the work file, I never delete off the faces, therefore the seats cannot be seen through the windows, however you see the body of the bus (yellow in color instead) )

The extrusion of the front part of the bus. This is the most challenging step to model. First I try to figure around how I extrude out parts from the body of the bus. I try to select the following faces I wish to extrude out of the polygon cube (body of the bus). The first time I tried the extruded shape is not correct. Then I undo it and redo it again. It does not look convincing and the shape, topology is wrong. It does not fit properly in the correct position. After trying for a few times. I decided to model the front part with a separate polygon. Follow by combining it together. Basically, just only the front part, it took me two to three days to figure it out and to complete it. In the end I am able to model the correct shape and fit in properly to the body of my model object.

With regards from the front segment I extrude the side for the placement of the wheels. I remembered in class, teacher had shown me the steps I should carried out in order to get the ideal shape. I try to recall the steps, first create a cylinder and scale the sides to 8 sided cylinder. ( reference for the wheel) With that as a reference I place it in the center, uses insert edge ring tool> cut the edges accordingly to the 8 sided cylinder> arrange the vertices as matches > made the vertices and align the edges straight. Select the appropriate edges and extrude it. However after extruding it and smooth it the shape looks distorted. Hence I guess there are some part I had model it wrongly. I try modeling it separately. This means I create a cube, following the same steps as said above , I try it again and again until I am satisfied with the shape when I smoothen it. Finally, I got my side for the placement of the wheels. Hence I just have to move this polygon and combine it with the front part (polygon).

Wheel, creating a wheel include 4 parts. The rim of the wheel, a thin pipe, a bigger pipe as a support, and the rubber tire. Before I start, I look at my real object, thinking/ planning on what are the steps I should do. So I decided to look into tutorial and take a look on how others model a wheel rim and I try it myself. First I create 2 pipe, one small and one big. Then place the small pipe in the center of the big pipe> select the face ( 2 by 2) and extrude out the faces> a tab (keep the faces together) need to be turn OFF. However, till I model to the end. I realize I forgotten the important steps which is to turn it OFF. I have to redo it again, after extruding the faces, I met with another problem, the faces does not fit properly to the big outer pipe. Thus , I have to scale it and arrange it in the right and order position.

Bottom Plane using a plane, I first need to adjust the size ( height,width) of the plane. After that placing it together, at first I combine the bottom plane and the body together. Then I realize actually they are two separate polygons/parts and also after placing it at the bottom of the bus, the plane intersect the wheel, hence I need to estimate the correct position for the plane accordingly and delete away the faces and edges. Now it fits properly.

Bottom plane ( Front extrusion) I model it wrongly. I use insert the edge ring tool to cut edges and select the front faces > extrude. I did not look and analyze the real object properly before modeling the parts. Hence after extruding, I scale it the opposite way, it should be scaling to make it big for the bottom then select the top face from the previous extrusion and extrude upwards>scale it down for a smaller face. I need to adjust in using the move tool and move it to the right position.

Text, by creating the text, Is simple although it has not been taught in class. The same thing I follow tutorial as a reference, but the tutorial shows 3D text( type bevel). Actually there are 4 types of text. Curve, Trim, Poly and Bevel. I try each of the type and compare it with the text of my real object and I touch the surface to see whether is it extruding out or something. First I try bevel, then I realize I am wrong. So I chose poly. But when the text is created, I use the move tool to move my text to the correct position , to my surprised the poly text consists of wireframe and poly. Only the poly can be move as whole. I am unsure till this steps. As the deadline is near, I decided to just take the poly text and delete the wireframe. I am done with the text.

Image plane. Just by adjusting the image plane, I have redo it for more than 5 times. It can be simple but arranging it to fit the size proportionately can be difficult. I place it wrongly, where is suppose to be a front view, I rotate in to place it both the back view. It is confusing.
