* Surface shadow improvementMika Salmela2014-10-225-12/+78
| | | | | | | | | Not allowing bias go below 0.001 prevents the shadow acne. Faulty formula for lighning direction. Task-number: QTRD-3382 Change-Id: Ided8bf423a961744ace8bef32ae18d6fa2c443ef Reviewed-by: Miikka Heikkinen <miikka.heikkinen@theqtcompany.com>
* Implement zooming to cursorMiikka Heikkinen2014-09-262-0/+11
| | | | | | | | | Zooming to cursor is now default operating mode of the default input handler. Task-number: QTRD-3263 Change-Id: I5699fc0ce7393059538972cd52f31f06d87e3d8d Reviewed-by: Tomi Korpipää <tomi.korpipaa@digia.com>

* Limit volume to axis rangesMiikka Heikkinen2014-09-104-116/+135
| | | | | | | | | The volume object that would go partially outside axis ranges is scale and repositioned so that it only renders the portion that is inside the axis ranges. Change-Id: I792494e437998ba6276f58fab645767276c1476d Reviewed-by: Mika Salmela <mika.salmela@digia.com>

* Add option to use low definition volume shader.Miikka Heikkinen2014-09-022-5/+122
| | | | | | | | Low definition volume shader samples the texture at even intervals, so it will sometimes skip texels, causing flickering. Change-Id: Iee6cb0e8893498b89ce1a40f34701a53d100283e Reviewed-by: Tomi Korpipää <tomi.korpipaa@digia.com>
* Pixel perfect volume shaderMiikka Heikkinen2014-09-012-69/+122
| | | | | | | | | Now the volume should render with pixel perfect accuracy. The drawback is that it is significantly slower than the old approximate solution. Change-Id: I4df7e9a28a27b56150c71a85a4c1fb69a215dabc Reviewed-by: Tomi Korpipää <tomi.korpipaa@digia.com>
