- | {{: | + | |
- | ===== Setting | + | On the main menu bar, we have **Open** |
- | Within the **Size and position** tab shown above, the most important thing to do is to show a test pattern, and then adjust the size and position tool to fit the projected output to your projection screen (or area), and also the **Invert X, Invert Y** and **Swap XY** check boxes. We have noticed that some projector manufacturers require one or more of these check boxes to be checked in order for the " | + | **Save settings of all projectors to default settings file** button forces |
- | ===== Setting | + | **Note:** when you press OK, all your settings for each hardware are saved to the system/ install of QuickShow and will be recalled later, but these save settings are for your convivence. |
- | Another important part of the Projector Settings window is the **Scan rate** tab, as shown below. | + | **Copy** and **Paste** Buttons allow you to copy all settings from one piece of hardware to others. This can be useful if you have 4 of the exact same lasers and get one tuned perfectly, you can paste to the rest of the hardware and they will all likely be just about the same. Saving you time from doing them all separately. |

- | **Wide Angle Compensation**: Wide angle compensation is a new check box in your scan speed tab of projector settings which will automatically slow scan speeds down when projecting at large scan angles. This has the benefit of lowering the heat inside the scanners, correcting “bent” corners in projection, and extending the life of your scanners. | + | ==== Test Patterns ==== |
+ | |||
+ | {{: | ||
+ | |||
+ | The Test patterns window allows you to display laser output on your hardware while you are tuning your system. Some that you will use for tuning may be the Orientation test for size and position, ILDA 30kTest for scan rate and color shift, and Grayscale test for color tuning. | ||
+ | |||
+ | To use, just select the pattern, and the hardware/ | ||
+ | |||
+ | ===== Size and Position ===== | ||
+ | |||
+ | On the **Size and Position** Tab you have the ability to scale your output on your projector. 100x100 means the control hardware will use the full extent of output that your system can use. Most users prefer to set this at 100x100 and leave everything else to be done in " | ||
+ | |||
+ | It's generally recommended for beam show content to only really use 95% of the maximum output and 50% size for graphic content. Setting this here keeps your lasers from pushing themselves to their limit all the time, so some users prefer to keep themselves from the ability to use the full size. | ||
+ | |||
+ | You may have some different systems in your setup that have different max scan angles or may be flipped differently from each other. To help keep all lasers acting the same, you may set slightly different max settings on each so they all act the same in programming and zoning. | ||
+ | |||
+ | |||
+ | ===== Scan rate ===== | ||
+ | |||
+ | A projectors **Scanrate** is how fast Quickshow will send data to your projector. Different projectors vary significantly how fast they can output laser data, and sending data to fast to some systems that cant handle that speed can damage your laser scanners. Because of this, its very important you set your scan speed to the correct setting. | ||
+ | |||
+ | {{: | ||
+ | |||
+ | When setting **Default sample rate** (scan speed), the first thing to do is check the manufacturers specification sheet. it will either be written as a "Scan Speed 30kpps" | ||
+ | |||
+ | **Minimum and Maximum Scan rate** - There are some effects inside QuickShow that allow you to slow down and speed up scanrate. For most users its recommended to set maximum to the same speed as your default scan rate and leave the minimum to default. Advanced users who are comfortable with overdriving their scanners could increase the maximum scan rate, but its not recommended. | ||
+ | |||
+ | Another thing to set in this tab will be **Color Shift**. Since scanners are mechanical tools, they have a recation time, or latency. Unlike the laser diodes which use digital drivers, they will not stay in time with each other. To compensate we have a color shift where output of color data and scan data are delayed. Most lasers that run at 30kpps will use a color shift of 4, 40kpps a shift of 5, and 20kpps of 3. How to check this using the ILDA test pattern is located at the end of this document. | ||
+ | |||
+ | **Minimum number of points** Keeps scanners from looping frames excessively fast which can lead to heat buildup and performance/ | ||

+ | |||
+ | {{: | ||
+ | |||
+ | Not all lasers use the same laser diodes inside the laser, so to help get the best color output form your projector, you first need to determine the **number and type of lasers** in your system, if its 1 color, 2 color, or 3 color RGB, or RGV. Most modern laser systems use RGB color systems. | ||
+ | |||
+ | Next you will need to determine the **color system type**, TTL means the lasers don't fade, Linear response | ||
+ | |||
+ | And lastly you can set the minimum and maximum voltages for each color channel with the **color output levels**. If your laser has a bit to much of a single color for your liking, you can lower the maximum power output on each channel to do a basic color calibration. Its unlikely your minimum voltage should need to change | ||
+ | |||
+ | ===== Vector display settings ===== | ||
+ | |||
+ | {{:quickshow: | ||
+ | |||
+ | ==== Spacing ==== | ||
+ | |||
+ | **Visible lines spacing** - the spacing (distance) between visible points. QuickShow measures spacing between two neighboring points | ||
+ | |||
+ | **Blanked lines spacing** - the spacing (distance) between blanked points. As a rule, the spacing for blanked lines can be several times more than that of visible lines. Two big of spacing can be dangerous for your scanners because of peak voltage and consequential overheating issues caused by this. | ||
+ | |||
+ | **Use nonlinear spacing for blanked lines** - nonlinear spacing places more points near the beginning and ending of a line and a bigger distance between points in the center of a blanked line. As a rule, this option works better for blanked lines. | ||
+ | |||
+ | ==== Anchors ==== | ||
+ | As a rule, a frame is a sequence of multiple visible vectors/points and blank line(s) in between. The place where a blanked line becomes visible, or a visible line turns to a blanked line requires additional anchor points for vectors. | ||
+ | |||
+ | When a visible line turns to a blanked line (end of visible line), QuickShow adds a few visible anchor points and a few blanked anchors after the line gets blanked. A similar process happens when a blanked line ends and starts a visible line. Here a few blanked and visible anchors should be added. Such points are never added between visible lines or between blanked lines (for this we have Angle optimization.). | ||
+ | |||
+ | **Visible line begin** - anchors at the visible line beginning. | ||
+ | |||
+ | **Visible line end** - anchors at the visible line ending. | ||
+ | |||
+ | **Blanked line begin** - anchors at the blanked line beginning, works together with “Visible line end”. | ||
+ | |||
+ | **Blanked line end** - anchors at the blanked line ending, works together with “Visible line begin”. | ||
+ | |||
+ | |||
+ | ==== Angle ==== | ||
+ | Angle optimization works for visible lines only and between visible lines only. If there is transition between a visible and blanked line, QuickShow adds anchors according to the Anchors section. | ||
+ | |||
+ | **Linear angle to anchor relation** - number of anchor points in a 180 degree turn. | ||
+ | |||
+ | **Custom Setting** - a diagram that allows setting the number of anchor points for turns of 100, 40, 60… 180 degrees. | ||
+ | |||
+ | ===== Track settings ===== | ||
+ | |||
+ | {{: | ||
+ | |||
+ | QuickShow generates special transitional (short) frames between the tracks/ | ||
+ | |||
+ | **Fixed point number** - the path always has the same number of points distributed between the start and end points of the path. | ||
+ | |||
+ | **Spacing** - the number of points in the path is calculated dynamically according to the distance between the starting and ending points. __**If the distance is less than one space, QuickShow will not generate the transitional path.**__ | ||
+ | |||
+ | **Beginning anchors** - number of blanked points (anchors) in the line beginning. | ||
+ | |||
+ | **Ending anchors** - number of blanked points (anchors) in the line ending. | ||
- | ===== Setting up the colors ===== | + | **Beam Generation Settings** - minimum point number. QuickShow has a specially designed, power optimized system for beam generation used for Target Beam Sequences. The system is most effective when Target Beams is using static beams. QuickShow takes the minimum points as a basis and distributes them between the beams dynamically. The Number of points may be bigger than the minimum. |
