+Hey ! 
+This week, More Shaders!
+
+What did you do this week?
+--------------------------
+The task assigned for this week was to explore more shader techniques which could be implemented using FURY and which would demonstrate the capability of FURY shader system. So i decided to work on implementing shading examples such as Gooch shading and reflection shader using textures.
+
+
+Below are the outputs of the techniques i worked on :

+
+Hey ! 
+This week, Picking Outline!
+
+What did you do this week?
+--------------------------
+We needed a Outline feature in FURY to indicate which model we choose in the scene. So the task assigned was to find options to achieve this. There were two ways to do this, 1. Using shader and 2. Using Vtk PolyData Silhouette. Despite trying multiple implementation methods the shader approach was not working . I also tried using VTKs inbuilt function , but there is a bug when i use some models. When i choose a model, it renders outline for every polygon , which is not what we want to achieve. The bug is shown below:

+
+What is coming up next week?
+----------------------------
+With the end of GSoC approaching soon, the next task is to create a PR which can help new users to test different shaders using UI to get started. 
+
+Did you get stuck anywhere?
+---------------------------
+I still was not able to figure out how we can achieve the outline effect. Am currently looking into other approaches we could use

+Google Summer of Code 2020 Final Work Product

+-  **Name:** Lenix Lobo
+-  **Organisation:** Python Software Foundation
+-  **Sub-Organisation:** FURY
+-  **Project:** `FURY - Improve Shader Framework <https://github.com/fury-gl/fury/wiki/Google-Summer-of-Code-2020>`__
+Introduction
+------------
+The current shader framework for FURY is based on VTK and lacks documentation to get started which can be overwhelming for new users. The objective of this project is to enable users to be easily able to understand and use the shader framework to render stunning visual representations of data. The project involves programming vertex and fragment shaders to generate effects for more immersive visualization.
+
+Proposed Objectives
+-------------------
+**Adding SDF actor to the API**
+
+ This actor uses raymarching to model actors using SDF. The method provides several actors including `ellipsoid`, `sphere` and `torus`.
+**Shader demos**
+
+ Use the FURY shader system to create and visualize different shading algorithms. Implementations include `SphereMap`, `Toon`, `Gooch` and `Vertex Noise`
+
+Unsubmitted Functionalities
+---------------------------
+**Spherical Harmonics using Shaders.**
+
+The spherical harmonics algorithm is used to generate spherical surfaces using biases and coefficients computed. The general approach to achieve this is computationally expensive. The idea proposed was to leverage the GPU hardware using shaders to provide a faster more efficient alternative to the current implementations. The second month of the coding period was devoted to the same task but unfortunately, the observed performance was quite unsatisfactory than the expected performance. Moreover, the output shape of the geometry was distorted. It was then decided to continue the work after the GSoC period and prioritize the task at hand.
+
+The Work in Progress can be accessed here. https://github.com/lenixlobo/fury/tree/Spherical-Harmonics
+
+**Dynamic Texture using Geometry Shader**
+
+Geometry Shaders provide a lot of flexibility to users to create custom geometry behaviors such as instancing. The idea was to create a dynamic Fur/Hair effect on top of a FURY actor. Unfortunately due to missing documentation on VTK geometry shaders and lack of resources, the project was not completed during the GSoC period. However, I will continue to try to solve the issue.
+
+The source code for the current progress can be accessed here. https://github.com/lenixlobo/fury/tree/Dynamic-Texture
+
+
+Objectives Completed
+--------------------
+**SDF based Actor**
+
+  The objective here was to provide an alternative approach to users to use SDF modeled actors in the scene. This actor is modeled using the raymarching algorithm which provides much better performance than conventional polygon-based actors. Currently, the shapes supported include ellipsoid, sphere and torus
+
+  *Pull Requests:*
+  **SDF Actor method:** https://github.com/fury-gl/fury/pull/250
+
+**Multiple SDF Actor**
+
+  The objective was to create a method through which multiple SDF primitives are rendered within a single cube. This task helped us explore the limitations of the shader system and also benchmarking the performance.
+
+  *Pull Requests:*
+  **MultiSDF Shader:** https://github.com/fury-gl/fury/blob/master/docs/experimental/viz_multisdf.py
+
+**Shader Demos**
+
+  The task here was to create a pull request showcasing the capabilities of the FURY shader system and to also provide examples or new users to get started with integrating custom shaders into the scenes.
+
+  *Pull Requests:*
+  **Shader Demos:** https://github.com/fury-gl/fury/pull/296
+
+
+
+Other Objectives
+----------------
+- **Tutorials**
+
+   Create Tutorials for new users to get familiar with the Shader System
+
+   *Pull Requests:*
+   - **Shader UI Tutorial**
+
+   https://github.com/fury-gl/fury/pull/296
+
+   -**SDF Actor Tutorial**

+   https://github.com/fury-gl/fury/pull/267
+
+- **GSoC weekly Blogs**

+Hey Everyone!
+Today marked the official end of the coding period for Google Summer of Code 2020. On this day I would like to take the opportunity to thank all my mentors and Soham who have shown immense support during this time and helped me grow not only to be a better programmer but also to be a better team member. While the GSoC period ends, I will try my best to be active and contribute to the project and help it grow.
+Cheers!
+
+What did you do this week?
+--------------------------
+This being the final week of GSoC , my task was to create a PR which showcases not only the shader capabilities of the project but also to create a example which integrates both the UI and shader system of project FURY. This example can help new users to get familiar with both the UI and shaders.
+Apart from this i also worked on a Toon Shader.
+
+The output for the above task is given below :

+
+What is coming up next week?
+----------------------------
+The next week I will work on the final GSoC documentation which explains what I worked on throughout the GSoC period. In case of any changes are requested by the mentors I will also try to implement them.
+
+Did you get stuck anywhere?

+With the help of Soham and the mentors this week went smoothly.
