Product Introduction

X Insight is a 3D integrated performance testing tool based on X 3D equipment. It is mainly able to quickly build, display, and analyze the performance of super-large content in large-scale scenarios. Load data with one click, process display, and analyze performance. The overall diagram is as follows:

Hardware Environment

Device model	Parameter Requirements
CPU	Intel i5 or faster
RAM	8GB or more , 16GB recommended
GPU	NVIDIA GeForce GTX 960 or faster

Software Environment

• Windows 7 SP1 or above (requires graphics driver to support OpenGL4.5 or above or DirectX11)
• Linux Ubuntu 13.10 or above / Neokylin 5.0 or above

Precautions

• The core of the hardware-related requirements is that the GPU driver supports DirectX11 or OpenGL4.4 or above

Main Features

The current main features are as follows

1. Cross-platform support, support Windows, Mac, Linux
2. Supports creating objects with custom vertex information. Basic primitives include: prototype, sphere, triangle, etc.
3. Support importing FBX model data
4. Support importing CAD model data
5. Support for importing point cloud (E57) data
6. Support scene effect display and performance analysis at the level of 10,000 test units
7. Support stress test scenarios and results, screenshot generation. (supports transparent layers)
8. Supports video recording and display of stress test results
9. Support environment correction, including sun position, scene floor, floodlight, fog and other effects
10. Support line style debugging mode such as triangle line surface
11. Support various debugging texture specific analysis in the rendering process
12. Support various memory, CPU, GPU, stack information, physical system performance, triangle vertices, DrawCall and other information based on the built-in performance optimizer
13. Different rendering links, function-level performance checking tools (only supported in Debug version). Used to accurately check performance consumption bottlenecks.

Development Tool Support

• Visual Studio 2015
• QT 5.14.0
• Xcode
• Gcc

Specific Steps

Import FBX model

Open the program, select the FBX file to import, if it does not exist, please manually copy the FBX file you want to test to the data directory of the program (any location is fine)

Click [Add FBX], wait a moment, and your FBX model will be displayed in the scene. The operation is as follows:

The effect after importing is as follows:

Other important configuration parameters:

• The number added to the scene: Node Count in the figure below
• X , Y margin , are the numbers of X and Y of multiple queues respectively (several rows and columns)
• Set Camera, because the initial position of many models is not necessarily standardized, many need to adjust some properties of the camera to see the effect. So please set the appropriate Z Near and Z Far at this time
• Find by pos / bound , this is the same reason as above, the position of the initially imported model has its own deviation, click these two buttons, you can get the current real initial position of the model, or the center position determined by the boundary.

Import CAD objects

The method of importing CAD is the same as importing FBX, the only difference is that please select the CAD file and UI content. As shown below

Please note that since the CAD format is a different format than FBX, the import may fail, please contact us.

At the same time, after the CAD data is imported, known reasons will cause additional crashes when closing the program, but it does not affect the use. This problem is more complicated, please wait for our subsequent version to fix it.

Import custom Element

If there are supporting artists, it is the most convenient way to help you make Element in the editor directly. Copy the node file directly to the data directory of the program, and then you can choose to use it in the program

Since Element is a built-in object, there is no import step, and the loading speed will be very fast.

Scene Reset

In the interface, click [remove all], and the content in all scenes will be cleared.

Click [Reload FileSystem], the loaded file system will be reset.

DF engine built-in object addition

Add cloud object

Add seawater object

Video Recording

After entering the program, when you want to record the content of the current visible window to the video, press F10, and the console window will prompt to start recording the video. . . . , when you want to stop recording at any time, press F11

Finally, the recorded video will be stored in the Bin/videorecord directory of the program in the form of a file. The video format is mp4

In the future, we will provide a way to stream the video in real time.

Windows Screenshot

Provide 3 different levels of screenshots, corresponding to the shortcut keys F6, F7, and F8. The format is PNG, and the save directory is under the bin/screenshots directory where the program runs

F6 screenshot non-test interface and pure window content of performance analyzer, as shown below

F7 screenshots all window content, excluding transparent channels, as shown below

F8 screenshots all window content, including transparent channels, as shown below

Performance Analysis

By default, DF Insight has turned on the performance analyzer, and you can see every detail in real time.

(Ctrl+S can be used to control display/hide)

The specific contents are:

Total overall consumption time

Update Update time period consumption time

Render CPU CPU consumption time during rendering time

Waiting GPU rendering time period GPU consumption time

Physics physics system consumes time

Heap heap allocation memory situation

Memory memory allocation usage

System memory usage consumed by the system

Textures texture allocation memory usage

Grasses grass object memory consumption

Terrains terrain object memory consumption

Samples texture sampling object memory consumption

The number of light objects in the Lights scene

Number of shaders loaded in the Shaders scene

The number of materials loaded in the Materials scene

Traiangles The number of triangular drawing faces within the current visible range

Primitives The number of basic primitives in the current visible range

For more detailed function-level rendering of each rendering link, microprofile can be used, and the effect is as shown in the figure below.

Click the Call Profile button to call it out.

Hot Key

Control related:

Ctrl+1 Show/hide the upper control panel Ctrl+2 Show/hide the rendering-related control panel

Ctrl+s show/hide performance optimizer shown below

Screenshot related:

F6 screenshots non-test interface and pure window content of performance analyzer

F7 screenshots all window content, excluding transparent channel

Video recording related:

F9 starts recording screen video, excluding performance analyzer and interface elements (the video is in MP4 format, stored in the bin/videorecord directory)

F10 starts to record the video of all content on the screen (the video is in MP4 format, and the storage location is under the bin/videorecord directory)

F11 stops recording video
