      I want to calculate the position of the camera, but I always get a vector of zeros.

      D3DXMATRIX viewMat; pDev->GetTransform(D3DTS_VIEW, &viewMat); D3DXMatrixInverse(&viewMat, NULL, &viewMat); D3DXVECTOR3 camPos(viewMat._41, viewMat._42, viewMat._43); log->Write( L"Camera Position: %f %f %f\n", camPos.x, camPos.y, camPos.z);

      Could anyone please shed some lights on this?

      I'm following rastertek tutorial 14 (http://rastertek.com/tertut14.html). The problem is, slope based texturing doesn't work in my application. There are plenty of slopes in my terrain. None of them get slope color.
      float4 PSMAIN(DS_OUTPUT Input) : SV_Target { float4 grassColor; float4 slopeColor; float4 rockColor; float slope; float blendAmount; float4 textureColor; grassColor = txTerGrassy.Sample(SSTerrain, Input.TextureCoords); slopeColor = txTerMossRocky.Sample(SSTerrain, Input.TextureCoords); rockColor = txTerRocky.Sample(SSTerrain, Input.TextureCoords); // Calculate the slope of this point. slope = (1.0f - Input.LSNormal.y); if(slope < 0.2) { blendAmount = slope / 0.2f; textureColor = lerp(grassColor, slopeColor, blendAmount); } if((slope < 0.7) && (slope >= 0.2f)) { blendAmount = (slope - 0.2f) * (1.0f / (0.7f - 0.2f)); textureColor = lerp(slopeColor, rockColor, blendAmount); } if(slope >= 0.7) { textureColor = rockColor; } return float4(textureColor.rgb, 1); } Can anyone help me? Thanks.

      ok, so, we are having problems with our current mirror reflection implementation.
      At the moment we are doing it very simple, so for the i-th frame, we calculate the reflection vectors given the viewPoint and some predefined points on the mirror surface (position and normal).
      Then, using the least squared algorithm, we find the point that has the minimum distance from all these reflections vectors. This is going to be our virtual viewPoint (with the right orientation).
      After that, we render offscreen to a texture by setting the OpenGL camera on the virtual viewPoint.
      And finally we use the rendered texture on the mirror surface.
      So far this has always been fine, but now we are having some more strong constraints on accuracy.
      What are our best options given that:
      - we have a dynamic scene, the mirror and parts of the scene can change continuously from frame to frame
      - we have about 3k points (with normals) per mirror, calculated offline using some cad program (such as Catia)
      - all the mirror are always perfectly spherical (with different radius vertically and horizontally) and they are always convex
      - a scene can have up to 10 mirror
      - it should be fast enough also for vr (Htc Vive) on fastest gpus (only desktops)

      Looking around, some papers talk about calculating some caustic surface derivation offline, but I don't know if this suits my case
      Also, another paper, used some acceleration structures to detect the intersection between the reflection vectors and the scene, and then adjust the corresponding texture coordinate. This looks the most accurate but also very heavy from a computational point of view.

      Other than that, I couldn't find anything updated/exhaustive around, can you help me?
      Thanks in advance

      It is a combination of fundamental RPG elements and challenging, session-based MOBA elements. Having features such as creating your unique build, customizing your outfit and preparing synergic team compositions with friends, players can brave dangerous adventures or merciless arena fights against deadly creatures and skilled players alike.

      This time with no grinding and no pay to win features.

      We're still looking for:
      1) 3D Character Artist
      2) 3D Environment Artist
      3) Animator
      4) Sound Designer
      5) VFX Artist

Sundog Announces SilverLining 5

Recommended Posts

Sundog Software today released version 5 of its SilverLining Sky, 3D Cloud, and Weather SDK for simulation and game developers. SilverLining 5 offers a new representation of storm clouds, providing more immersive flight training in dangerous weather conditions.

“SilverLining 5 includes a new library of hand-modeled cumulonimbus thunderheads and towering cumulus clouds,” says Frank Kane, founder of Sundog Software. “Our team worked from photographs taken of real storm clouds in various stages of development, to deliver a convincing visual simulation of bad weather from any altitude.” A cloud editor application is also included to allow customers to modify or add their own cloud models as desired.


SilverLining 5 also delivers improved performance in stormy conditions, due to several new optimizations in how its clouds are rendered. These optimizations result in SilverLining’s best performance to date in other weather conditions as well. SilverLining is compatible with round-Earth simulation systems and includes sample integration code for popular frameworks such as OpenSceneGraph.

“Simulating the sky and weather brings a challenging set of requirements for developers of virtual training environments,” Kane expanded. “We allow our customers to convincingly simulate any weather, at any time, at any place, while making integration of our software as simple as possible and its overhead as low as possible.”

SilverLining 5 is available for licensing today at http://www.sundog-soft.com/ on a per-application basis. Free trial versions and demos are also offered for evaluation purposes.
