Install Driver Printer Canon Ip 2770 Ubuntu 11.10

Canon IP 2770 Printer not automatically detect on my Ubuntu laptop, i've download and try to install the driver, but i can't installed. But i've the solution today. For download IP 2770 printer driver you can go to there or for another Canon printer driver you can download through Michael Gruz ppa. Here i write how to install Canon IP 2770 driver

Download the Canon IP2770 Driver
Extract the downloaded file
Just run the install.sh if you can't run install this you need following this step

Open the install.sh with texteditor like gedit.
Delete line 1224 until 1250 which contains the following code

C_FUNC_get_system()
{
 local c_system_rpm=""
 local c_system_deb=""

 ## Judge is the distribution supporting rpm? ##
 rpm --version 1> /dev/null 2>&1
 c_system_rpm=$?

 ## Judge is the distribution supporting dpkg(debian)? ##
 dpkg --version 1> /dev/null 2>&1
 c_system_deb=$?

 ## rpm and deb are error, or rpm and deb are no error, is error ##
 if [ $c_system_rpm = 0 -a $c_system_deb = 0 ] || [ $c_system_rpm != 0 -a $c_system_deb != 0 ]; then
  printf "$L_INST_COM_01_02"
  return $C_ERR_CODE
 else
  if test $c_system_rpm -eq 0; then
   C_system="rpm"
  else
   C_system="deb"
  fi
 fi
 
 return 0
}

Replace with this code

C_FUNC_get_system()
{
C_system="deb"
return 0
}

After do that, try click twice on install.sh for instalation
Choose run with terminal
Insert your password and plug your printer device

For 64bit user, there is some trick from Aditia

You don't need changing the install.sh file
Don't plug your printer device during instalation
Just write this command on your terminal (make sure your terminal is accessing the folder where you save the file)

sudo dpkg --force-architecture -i cnijfilter-common_3.30-1_i386.deb

sudo dpkg --force-architecture -i cnijfilter-ip2700series_3.30-1_i386.deb

After do that plug your printer device and you will get notification that your printer ready for using

I hope with this tips and trick you can using your printer in Ubuntu.

Blender

Alpha Channel Mapping

This tutorial made by friend, Aditya. Now, he is making an open movie like durian i think. He write tutorial about his project. The project is about motorcycle thieves you can view the project here. The project using Bahasa Indonesia language, so i've contact him to translate the tutorial into english on this blog.

Today, i want write in english version of Aditya tutorial About Alpha Channel Mapping in Blender. In Blender Cycles not yet supported render alpha channel from adds on import image as plane, so we need minor adjusments to render it with cycles.

Open Blender. Add plane using Shift A > Mesh > Plane or download the source file here

Change the render engine from Blender Render to Cycles Render

Select new material on properties and new (add new material)

Give the material name relevance with the object, for example is daun. Daun mean leaf

Change the surface diffuse to add shader. It cause a buildup of two types material with blending type add

In first material shader is Diffuse BSDF.

And for second material shader is Transparent BSDF

Click small icon on first shader and select image texture

Open image on first shader

Browse image file (not alpha channel).

Repeat it on second shader. Click the icon and select image texture

Open image on second shader.

Browse image file (alpha channel).

You can make the alpha image using GIMP. The example of alpha image using white for alpha channel and black for the image. White background is invisible when rendering and black color will be seen in accordance with the shader diffuse
Separate the 3D view with dragging + on top of window

Change the first 3D view into Image Editor

Select the plane and go to Edit Mode with TAB on keyboard > Press U on keyboard > Unwrap

Change the viewport shading to material

After the material appears, adjust vertex on image editor using Grab, Rotate and Scale like on the 3D view.

And change viewport shading to rendered.

You will got this image

Duplicate this plane and adjust lighting, position, camera and other for the best result like this

With this way, you can make like this

Want more about this stuff? Keep update on malingmotor blog's. I hope this tutorial helpful and can enjoyed by you. Just leave comment for suggestion. I want it ;)

Animation

Multiple Camera With Different Path Animation Start

A few days ago, i've problem with camera and path animation. When i want create on scene with 3 camera and 3 curve for camera path animation. The problem is how to moving every camera with different starting frame? Because for default every camera will be start at first frame. I don't know how to explain what i want. It's just simple ilustration for camera what i want.

simple ilustration

I hope you understand with my illustration above.

First i have cam_01 and curve_01. I want cam_01 following curve_01 from frame 1 untill frame 100. Cam_01 need 100 frame to fly arround curve_01.
Second, i have cam_02 and curve_02. I want cam_02 following curve_02 from frame 20 until frame 40. Cam_02 need 20 frame to fly from starting point to end point at curve_02.
Third, i have cam_03 and curve_03. I I want cam_03 following curve_02 from frame 75 untill frame 90. Cam_03 need 15 frame to fly from starting point to end point at curve_03

For problem like me don't using offset and other, its really dont help us! It make us confuse. And my friend give me great solution like here:

Add a follow path constraint to every camera and set the path. ex: cam_01 with curve_01.
Selection the curve > object data > path animation.
Frames mean how long this must spend from starting point to end point. Evaluation time mean where is place of the object. I just little confuse to explain that. I'll give example, i hope you understand
Like my problem above, i want cam_02 start following curve_02 at frame 20 until 40. So you get the duration from start point to end point of curve. It's 20frames. So you need set Frames at path animation to 20.
Now go to frame 20. On frame 20 you have 0.00 Evaluation Time. Insert keyframe on this. Just press i button over the icon, and the color will be changed.
And go to frame 40. On frame 40, change the Evaluation Time to 20, because long of the curve is 20frame. So the camera will be moving into end point of curve. Insert keyframe again like before step.

It's the timelapse video to do the tutorial above

Thank Richard for help me to solve this problem! You can download the blend file of this ilustration here.

Bouncing Ball Rigging Blender Tutorial

Bouncing Ball, is one of the simplest models to learn 12 principles of animation. Therefore, starting from the modeling, rigging material up to a very simple and uncomplicated. The model can simply use the Sphere with the necessary rigging. Why not elaborate? because the ball we do not need to make rigging the hand. Simply rigging an armature with 3 bone will suffice. Here is step by step to create a simple rigging to bounce ball.

simple character rig

Open blender and delete the default cube > change view to front ortho [Numpad 1 (front view)> Numpad 5(orthographic / perspektif] > Add [Shift A] > Mesh > UV Sphere > Setting Segment: 16 dan Rings: 8

step one

Go to Edit Mode [TAB] > selection the lowest Vertex > Snap [Shift S] > Cursor to Selected

step two

Back to Object Mode [TAB] > Wireframe View [Z] >Add [Shift A] > Armature > Single Bone

step three

Back to Solid View [Z] > Object Data > Display: activate B-Bone dan X-Ray.

step four

Make sure the armature is right in the middle of the UV Sphere. To be sure, we can look at using Quad View [Ctrl + Alt + Q]. After fitting in the middle, to return to the previous display by pressing the same button [Ctrl + Alt + Q].

step five

Before proceeding to the next step, we need to know first armature and Bone, in order to distinguish between the armature and Bone

introduction to armature component

Bone can be interpreted as a bone. While the armature is a collection of bone (bone). Thus, the armature consists of a Bone
With the armature selected into edit mode [TAB]> selection of the top of the Bone and pull in the direction of axis Z [G> Z] (Do not Rotate [R] and Scale [S] the Bone)> Bone Position under UV Sphere, as in the image below. To ensure the bone ends up at the bottom vertex snap to use [Shift S] > Selection to Cursor

step six

Still in Edit mode, Add [Shift A]> appears a new bone> moved to Object Mode [TAB]> UV Sphere Selection> Edit Mode Login [TAB]> Selection topmost vertex> Snap [Shift S ]> Cursor to Selected> Go to Object Mode [TAB]> Selection bone ends up> Snap [Shift S]> Selected to Cursor> Add [Shift A]. Total bone there are 3.

step seven

step eight

Give name for each bone with clicking Bone menu. Lowest bone with name ground, center bone with name body, top bone with name control.

step nine

Still in Edit Mode, the selection body bone. Parent with ground and activate Connected. Enable Deform> Segment 12.

step ten

Go to Pose Mode [Ctrl TAB] > Bone Constraint > Add Constraint > Stretch To > Target: Armature, Bone: control

step eleven

Go to Edit Mode > Select control bone > Parent to ground.

step twelve

Back to Object Mode > selection the UV Sphere > Go to Edit Mode > Select All [A] > Object Data > Vertex Group > Add > Give name body (name of vertex group must be same with bone name, case sensitive) > Assign

step thirteen

Modifiers > Add Modifier > Armature > Object: Armature dan Vertex Group: body.

fourteen

To animate the UV sphere we just moving control bone in pose mode. And if we want to forward or backward just moving the ground bone

test on pose mode

If you feel challenged and want to better please try modeling a more complicated course. Hopefully useful dan you can enjoying this simple tutorial :)
