Hi, can someone please explain why this is giving an assertion EyePosition!=0 exception?
_lightBufferVS->viewMatrix = DirectX::XMMatrixLookAtLH(XMLoadFloat3(&_lightBufferVS->position), XMLoadFloat3(&_lookAt), XMLoadFloat3(&up));
It looks like DirectX doesnt want the 2nd parameter to be a zero vector in the assertion, but I passed in a zero vector with this exact same code in another program and it ran just fine. (Here is the version of the code that worked - note XMLoadFloat3(&m_lookAt) parameter value is (0,0,0) at runtime - I debugged it - but it throws no exceptions.
m_viewMatrix = DirectX::XMMatrixLookAtLH(XMLoadFloat3(&m_position), XMLoadFloat3(&m_lookAt), XMLoadFloat3(&up)); Here is the repo for the broken code (See LightClass) https://github.com/mister51213/DirectX11Engine/blob/master/DirectX11Engine/LightClass.cpp
and here is the repo with the alternative version of the code that is working with a value of (0,0,0) for the second parameter.
Hi, can somebody please tell me in clear simple steps how to debug and step through an hlsl shader file?
I already did Debug > Start Graphics Debugging > then captured some frames from Visual Studio and
double clicked on the frame to open it, but no idea where to go from there.
I've been searching for hours and there's no information on this, not even on the Microsoft Website!
They say "open the Graphics Pixel History window" but there is no such window!
Then they say, in the "Pipeline Stages choose Start Debugging" but the Start Debugging option is nowhere to be found in the whole interface.
Also, how do I even open the hlsl file that I want to set a break point in from inside the Graphics Debugger?
All I want to do is set a break point in a specific hlsl file, step thru it, and see the data, but this is so unbelievably complicated
and Microsoft's instructions are horrible! Somebody please, please help.
I finally ported Rastertek's tutorial # 42 on soft shadows and blur shading. This tutorial has a ton of really useful effects and there's no working version anywhere online.
Unfortunately it just draws a black screen. Not sure what's causing it. I'm guessing the camera or ortho matrix transforms are wrong, light directions, or maybe texture resources not being properly initialized. I didnt change any of the variables though, only upgraded all types and functions DirectX3DVector3 to XMFLOAT3, and used DirectXTK for texture loading. If anyone is willing to take a look at what might be causing the black screen, maybe something pops out to you, let me know, thanks.
Also, for reference, here's tutorial #40 which has normal shadows but no blur, which I also ported, and it works perfectly.
Is Direct3D 11 an api function like glMemoryBarrier in OpenGL? For example, if binds a texture to compute shader, compute shader writes some values to texture, then dispatchCompute, after that, read texture content to CPU side. I know, In OpenGL, we could call glMemoryBarrier before reading to assure that texture all content has been updated by compute shader.
How to handle incoherent memory access in Direct3D 11? Thank you.
Atum engine is a newcomer in a row of game engines. Most game engines focus on render
techniques in features list. The main task of Atum is to deliver the best toolset; that’s why,
as I hope, Atum will be a good light weighted alternative to Unity for indie games. Atum already
has fully workable editor that has an ability to play test edited scene. All system code has
simple ideas behind them and focuses on easy to use functionality. That’s why code is minimized
as much as possible.
Currently the engine consists from:
- Scene Editor with ability to play test edited scene;
- Powerful system for binding properties into the editor;
- Render system based on DX11 but created as multi API; so, adding support of another GAPI
- Controls system based on aliases;
- Font system based on stb_truetype.h;
- Support of PhysX 3.0, there are samples in repo that use physics;
- Network code which allows to create server/clinet; there is some code in repo which allows
to create a simple network game
I plan to use this engine in multiplayer game - so, I definitely will evolve the engine. Also
I plan to add support for mobile devices. And of course, the main focus is to create a toolset
that will ease games creation.
