Modeling Toyota Celica In Blender

oct10/31/04

Introduction

I modeled this car to learn the modeling of one of my favorite machines

especially to increase my modeling skills. Now as most of you will agree

modeling a complete car first time is quite complex. I did achieved

satisfactory results from it in terms of quality and experience :), but the

results could have been better. I have described the steps through which I

modeled body of the car and I release this as tutorial in hope it will benefit

someone.

Conventions used

Topic Car modeling (Toyota Celica) using Sub surfaces.

Level : Intermediate.

Mesh Available YES

Icons Used Note, and Tip

Shortcut Keys : For Blender are marked by BOLD.

Special Names : Certain repeatable names used are in italics.

Since this is intermediate level tutorial I expect people to complete the in

between step themselves. In any case the start-ups will definitely benefit

from it. This tutorial was done for blender, but I think it can easily be

applied to other modeling packages.

Since most of the cars have symmetric body on both sides we can just

model single half of the car and upon completion can mirror and join the

meshes to get the full mesh.

Let's get our hand's dirty

Step-1. First thing in prior to start modeling is to get the blueprints and

any other reference (photographs) for the model under way. I myself did

not searched for the photographs of Toyota Celica model, as I was very

anxious to start. I however got the blueprint from http://www.suurland.com.

It is recommended to look at more resources like photographs of the model,

as it is likely that you will get the better idea of its form and shape.

Second step is to set them up in Blender view ports like the Img below. I

used four view ports one for each side of the blueprint. It helps to correctly

visualize the contours of the surface during modeling as you can see most

of the blueprints offer views from top, left, back and front. First adjust

images in same proportions in an image editor like Gimp. Make sure the

proportion like height widths of the blueprints overlap each other perfectly.

Use scale, shrink on the images etc.

My method to check the size was by inserting all sides of blueprints in

different layers in GIMP. I then marked each side with red lines and then

made sure that width covered by front view is same as width of back view

and also the top view by either scaling or shrinking as the case may be.

Similarly I adjusted the height.

After you are done adjusting the Images save them differently and then

bring images into view port background. Keep your mouse over the view

port and press 'Ctrl+F7' (Depreciated shortcut in Blender 2.3x above

instead click on the view>>Background Image) a window will pop up, locate

the path for the images of the blueprint. Repeat this step for all four

images. Your blender window will look something like Img-2.

Img2.Images loaded in four view ports

Note: Before loading images (blueprints) make sure they are matched equal in resolution

otherwise you will have to adjust the size in the background properties, and this may not

produce desirable results.

Step-2. Ok done that now what? There can be different approaches to

starting modeling the car body. I choose to model the front side of the car

body, which covers the tyre (we will call it tyre_cover from now on). In top

view port place a square mesh and extend it along the contour of the

tyre_cover (towards left in top view Img-3) adjust the direction in first in

the top view port and then in other view ports.

If you are new to modeling then for you this may seem difficult to switch

between the view ports but it is a good idea to work and see the changes in

other view ports at the same time because every now and then the mesh

will get distorted during movements in one view-port. By observing and

little patience you will enjoy it gradually. After few extrusions your mesh will

look like as in Img-3.

Img-3.The tyre-cover mesh initially in top view port

Note : Now since we will be using Sub-Surf we need to have very less number of edges. The

reason for lesser number of divisions in mesh is that sub-surf will handle the smoothness for

us. Try to observe the effect on the mesh the Sub-surf function have by switching it on and

off (Press F9 and locate Sub surf in Buttons Menu). Adjust the curves of the mesh by tracing

the background image with minimum required lines/divisions just to get underlying shape in

correct proportion.

Select outer vertices (edge) of tyre_cover and extrude it towards the tyre

area following the shape of the car body see Img-4. To maintain the

contour of the mesh again follow it in other view ports.

Step-3 . Now we will make tyrecutout in the tyre cover mesh.

After Step-2 left click just above the end of the tyre-cover to place the

cursor (see Img-5a). Get into Side view and place the cursor at the middle

of the tyre (see Img-5b). Add a circle of 16 vertices. In the Fig I had exited

the mesh edit mode before adding the circle but you can do it in edit mode

also. The circle will provide good starting point to make the tyre cut out in

the tyre cover mesh.

Step-4. Get out of edit mode and go in to side view port. Select and Join

both the meshes ('Ctrl+J') (No need if you added the circle in Edit mode of

tyre cover mesh). After joining we need to add faces between circle and the

tyre cover mesh. Get into Edit mode select judicially three or four

(desirable) vertices then press "F" to add a face between them, follow the

Img-7a for help.

After joining the middle part of the circle you can extrude the faces from

the bottom part of the circle and do some join and face creation to get

complete mesh. if you need to add new independent vertices you can use

"Ctrl+Right click" combo.

Follow the above methods to get the mesh like in Img-7b. Go through all

the view ports to adjust the vertices so that proper contour of the tyre cover

mesh is retained as in the blueprint.
